At the beginning of each year, people flock to gyms to finally tackle their New Year's resolutions to get in shape, be healthier, and/or achieve the six-pack abs of their dreams. For some, that means hiring the services of a personal trainer who can give them the one-on-one attention they need to achieve their fitness goals. But personal trainers do more than just supervise your push-ups and ask you to do more reps: They talk to you about your eating and sleeping habits, sometimes see you cry, and might even end up earning an invite to your wedding. Here are a few insider secrets personal trainers shared with Mental Floss about their jobs.

1. Personal trainers really don’t like it when you’re late.

Several of the trainers Mental Floss spoke to said their biggest pet peeve is when clients show up late to their session. After all, the trainer has created a plan for the workout, and it’s frustrating to have to adjust that plan to accommodate the shorter workout.

“You’re kind of wasting your money,” says Ackeem Emmons, a personal trainer who began his career at Equinox, later started his own training business, and now works with Aaptiv, an audio-based workout app. “It’s so funny, because [clients] think they’re getting over on me—when you’re just short-changing yourself.”

2. Their hours aren’t as flexible as you think.

“They tell you [that] you can make your own hours,” Emmons explains. “That’s a lie. I wake up at 4 or 5 every day, because people either want to train before work or after work.” That means busy mornings and evenings, and inevitable afternoon downtime for trainers.

3. The salary for personal trainers varies widely ...

According to the Bureau of Labor Statistics, the median income for fitness trainers and instructors across the U.S. is a little more than $39,000 a year, or roughly $18.85 an hour. But that’s just the median: The pay can vary quite a bit between location (in California, the average fitness salary is closer to $50,000), clientele (celebrity trainers can command hundreds of dollars per hour), the facility (a trainer at a private gym typically makes more than someone working at a local rec center), and certification levels.

4. ... and so do the qualifications.

There are numerous certifications available, which can boost earning power and add to a trainer’s potential client base. Organizations such as the American Council on Exercise (ACE), the National Academy of Sports Medicine (NASM), and the National Strength and Conditioning Association (NSCA) all offer training manuals and certifications designed to make sure that anyone who calls themselves a personal trainer is well-versed in how the body works, nutrition, and injury prevention. In addition to general athletic certifications, there are specific courses for different exercise techniques, like using barbells, and for training specific populations, like people with chronic diseases or disabilities.

Some certifications are more rigorous than others, and some gyms are more stringent than others about the exact certifications their trainers hold, but in general, most trainers are always working on new certifications to add to their depth of knowledge. “I like to do it at least every couple of months to just learn something new,” Emmons says.

5. Personal trainers know when you’re not bringing your A-game.

Trainers can tell when you’re not totally focused on your workout, and they may pause the session to figure out why. “You have to figure out the reason why their mind is somewhere else,” explains Karyn Toffolo, a trainer who provides nutrition and fitness coaching through her company Happy Belly Strong as well as working at several New York City-area gyms. Solving that mental puzzle can be more important in the long run than it is to "kick their ass and give them this hard workout.”

Sometimes, however, the reason someone is distracted is much more simple. “I’ve had people come in drunk before,” Toffolo says. “You can just tell they’re not paying attention. So I have sent people home.”

6. Many clients come in with unrealistic expectations.

“A lot of people come in and say this actor put on 20 pounds of muscle in three months and I want the same result,” says Sean Collins, the co-owner and head powerlifting coach at Murder of Crows Barbell Club in Brooklyn. Goals like that are not in reach for the vast majority of the population—certainly not without performance-enhancing drugs—and he has to be the one to explain that. As Emmons puts it, “I’m a trainer, not a magician.”

They get a lot of very stereotypical requests, too.“Men all want huge arms, a big chest, and six-pack abs. And they need it by the 14th, because they’re going on vacation in two weeks,” Emmons says. “And women always want the triceps, the glutes, the inner thighs, and a six-pack—those are always the main things.”

7. Personal trainers also want to know about your diet.

Though most personal trainers aren’t nutritionists (Toffolo is an exception), helping clients eat right is still a big part of most fitness plans, according to Lacey Stone, a bi-coastal fitness expert who offers private training, group classes, boot camps, and virtual training, in addition to appearing as a celebrity trainer on E!’s Revenge Body With Khloe Kardashian. "I make certain that they have some kind of a higher protein/carbohydrate fuel before they work out," she says, because their body needs that fuel to perform.

Some of the education is just the basics. Stone says her clients often ask things like, "'Should I do keto? Should I fast? Should I do paleo?' I'm like, let's not worry about that until you even get like, what a vegetable is." (Stone is currently helping to launch a new line of milk-based protein shakes, called Core Power high protein milk shakes, so she likes to recommend those for an after-workout snack.)

“A lot of people come in with misconceptions about food—like someone will come in and say, ‘I haven’t eaten a carb in like four weeks,’” Collins says. “An important part of increasing muscle mass is increasing carb consumption. Sometimes they think fat will make you fat. They think too much protein will kill you, or too much carbohydrates will give you diabetes.” Part of the job of a personal trainer is to help re-educate clients on the role of food in their lives. That means not just telling people not to eat five slices of pizza in a row, but talking about what they're eating, when they're eating, and how that impacts their workout.

8. If they don’t ask about scheduling more sessions, it’s probably because they don’t want you to.

Not every client-trainer relationship works out, and sometimes trainers would prefer to let certain clients go. (Clients who are perpetually flaky or do nothing but complain throughout their sessions might not be asked back.) Of course, they try to be diplomatic about it. “I wouldn’t say I fired them,” Toffolo says of some former clients, “because they are paying me for sessions.” But if she doesn’t enjoy working with a client, when it comes time to schedule and pay for a new batch of sessions, “I just won’t ask if they want to renew.”

It’s not always personal, though. Toffolo works as a trainer at gyms like Brooklyn Boulders and Drive 495, and she occasionally hands her clients off to another trainer at the facility who might be better suited to helping them achieve their goals. For instance, if someone is rehabbing an injury, she is more likely to refer them to one of her colleagues with physical therapy experience.

9. Sometimes their sessions involve tears.

Stone says a fair amount of her clients end up crying at some point during the course of their training with her. “A big part of my program is getting people mentally and emotionally healthy before I can get them to do what I want physically,” she explains. Occasionally, that means tears—but “not sad tears. It's like, realization tears. It's like, finding your soul again tears.”

Collins deals with tears occasionally, too. “In power lifting, you can train for three to four months for one specific competition,” he says. So when people feel like they have fallen short of their goals when that big competition comes, it gets emotional. “I have had to manage a lot of tears,” he explains. “Any kind of fitness professional has to have a high level of empathy. I think the best ones out there are the ones who can completely understand why this is so upsetting to an individual.”

10. Personal trainers can get very close with their clients.

Personal training includes sharing a lot of intimate details about your life, like your diet, weight goals, sleep routine, and more, and as a result, trainers form tight bonds with many of their clients. Sometimes, "it can be more of a therapy session" than a workout session, Toffolo says. (That may happen whether the trainer likes it that way or not—"I’ve had a lot of people definitely share more than I wanted to," she adds.)

But Toffolo sees the client-trainer relationship as more of a friendship than a straight business relationship. She trains some clients for years on end, and has even been invited to some of their weddings. “It’s just nice to have that type of rapport with someone. It makes time go by quicker.”

11. They don’t need a big space to work …

Toffolo does house calls, and while some condo and apartment buildings feature high-end gyms, she doesn’t need a lot of space to work. “I can utilize a space as small as a closet,” she says. “I can manipulate [the program] so that it works with whatever the environment that I’m in.” That includes moves like stepping up onto benches, sprinting up stairs, and other moves that use the client's own weight as resistance.

12. … or fancy equipment.

Stone says that if there’s a few basic exercises she recommends to everyone, it’s squats, push-ups, and crunches—all things you don’t need a gym to do. “They've been around forever because they work,” she says. “I’m always like, ‘Get the basics down before you’re throwing a medicine ball around.’"

13. Personal trainers work with a lot of future brides.

Many personal trainers have a number of clients who are looking to get or stay fit for their wedding day. Stone and Toffolo both say they’ve had clients come on for just a few weeks or months prior to their wedding. “I had a lot of brides this summer,” Toffolo says, whose goal was “making sure they look good when they go down the aisle.”

While it may seem unrealistic to hope for dramatic changes just a few months before an event, with the right dedication, some of those pre-wedding workouts can yield impressive results. “I just had someone that lost 30 pounds with me in like seven months,” Stone says. “She looks unbelievable. She's been super inspiring.”

14. Yes, they heard you fart.

Everyone is human, and inevitably, a client will let a fart slip out during a workout. “It happens,” Toffolo says. “Most of my clients now I’m pretty close with, so I pretty much just laugh it off.”

15. Not all of them appreciate your New Year's resolution.

"The New Year’s resolutioners, they’re a little bit of my pet peeve," Toffolo says. "They take a lot of space at the gym for maybe one month," but aren't typically dedicated to sticking around for the rest of the year. "We make good money around this time of year, but usually, the New Year's resolutioners die down in February."

16. Personal trainers have to fit in their own workouts, too.

Personal trainers may spend a lot of time in the gym, but observing and coaching other people’s workouts isn’t the same as doing their own. In fact, Emmons says, “Not every personal trainer is in shape. As much as you’re training other people you have to train yourself.”

For Collins, being a trainer has actually made it harder for him to keep up with his own workouts. “Opening up a gym and coaching people has been the worst thing I’ve ever done for my own athletic endeavors,” he says. “There’s so much you have to get done as a business owner and a trainer, and so many things you have to do outside of client-facing hours.” That includes scheduling sessions, emailing clients, and coming up with new programs. As a result, he just doesn’t have the time he once did to focus on his own fitness goals.

But how much time a trainer spends on their own fitness depends on what training they’re doing, too. While Collins doesn’t get much of a workout coaching powerlifters, Stone leads classes at Flywheel, which specializes in indoor cycling. Though she may not be huffing and puffing as much as her students, she’s working out as she’s teaching. “When I’m working out, I can talk, because I'm at a high level of fitness,” she explains. “They're working out with me, so they get to actually see me doing what I'm telling them to do, five days a week.”

And though personal trainers love fitness, motivation can be as be as much of a problem for them as it is for you. “I’m just like everyone else,” Emmons explains. “I don’t want to work out every day—sometimes I just want to relax and catch up on my Netflix shows.” But he’s got to get himself to the gym anyway, because it’s his job.

Looking to Downsize? You Can Buy a 5-Room DIY Cabin on Amazon for Less Than $33,000

Five rooms of one's own.

If you’ve already mastered DIY houses for birds and dogs, maybe it’s time you built one for yourself.

As Simplemost reports, there are a number of house kits that you can order on Amazon, and the Allwood Avalon Cabin Kit is one of the quaintest—and, at $32,990, most affordable—options. The 540-square-foot structure has enough space for a kitchen, a bathroom, a bedroom, and a sitting room—and there’s an additional 218-square-foot loft with the potential to be the coziest reading nook of all time.

You can opt for three larger rooms if you're willing to skip the kitchen and bathroom.Allwood/Amazon

The construction process might not be a great idea for someone who’s never picked up a hammer, but you don’t need an architectural degree to tackle it. Step-by-step instructions and all materials are included, so it’s a little like a high-level IKEA project. According to the Amazon listing, it takes two adults about a week to complete. Since the Nordic wood walls are reinforced with steel rods, the house can withstand winds up to 120 mph, and you can pay an extra $1000 to upgrade from double-glass windows and doors to triple-glass for added fortification.

Sadly, the cool ceiling lamp is not included.Allwood/Amazon

Though everything you need for the shell of the house comes in the kit, you will need to purchase whatever goes inside it: toilet, shower, sink, stove, insulation, and all other furnishings. You can also customize the blueprint to fit your own plans for the space; maybe, for example, you’re going to use the house as a small event venue, and you’d rather have two or three large, airy rooms and no kitchen or bedroom.

10 Secrets of Epidemiologists

Unless you know an epidemiologist or are one yourself, those “disease detectives” might not have occupied a very large portion of your brain. Last year, that is. Now, with the coronavirus pandemic at the top of mind—and at the top of so many headlines—there’s a good chance you’re at least aware that epidemiologists study diseases.

To be more specific, the Centers for Disease Control and Prevention (CDC) defines epidemiology as “the study of the distribution and determinants of health-related states or events in specified populations, and the application of this study to the control of health problems.” So what exactly does this mean? Mental Floss spoke with a few epidemiologists to shed light on what they do, how they do it, and which germ-friendly foods they avoid at the buffet.

1. People often mistake epidemiologists for skin doctors.

Since the word epidemiologist sounds like it might have something to do with epidermis (the outer layer of skin), people often think epidemiology is some offshoot of dermatology. At least, until the coronavirus pandemic.

“Prior to that, no one knew what I did. Everyone was like ‘Oh you’re an epidemiologist—do you work with skin?’” Sarah Perramant, an epidemiologist at the Passaic County Department of Health Services in New Jersey, tells Mental Floss. “I would be rich if I had a dollar for every time I got asked if I work with dermatologists.”

2. Epidemiologists don’t discover a new disease every day.

Though some epidemiologists do look for unknown diseases—certain zoonotic epidemiologists, for example, surveil wildlife for animal pathogens that might jump to humans—most are dealing with diseases that we’re already familiar with. So what do they do every day? It varies … a lot.

Epidemiologists who work at academic or research institutions undertake research projects that help determine how a disease spreads, which behaviors put you at risk for it, and other unknowns about anything from common colds to cancer. But it’s not just about devising experiments and studying patient data.

“I like to tell my friends and family that my job is about four different jobs in one,” Dr. Lauren McCullough, an assistant professor in the department of epidemiology at Emory University’s Rollins School of Public Health, tells Mental Floss.

Writing, she says, is “the most important part.” It includes requesting grants, devising lectures and assignments, grading her students’ work, writing about her research, and more. She also sits on admissions committees, reviews other epidemiologists’ studies, and oversees the many people—project managers, data analysts, technicians, trainees, etc.—working on her own research projects.

Those who work in the public health sphere are often monitoring local outbreaks of diseases like the flu, Lyme disease, salmonellosis, measles, and more. If you test positive for a nationally notifiable disease (any of about 120 diseases that could cause a public health issue), the CDC or your state health department sends your electronic lab report to the epidemiologist in your area, who’s responsible for contacting you, finding out how you got sick, and telling local officials what steps to take in order to prevent it from causing an outbreak.

3. Epidemiologists have to make some uncomfortable phone calls.

Epidemiologists sometimes have to ask pretty personal questions about drug use and sexual activity when trying to figure out how someone got infected, and not everyone is happy to answer them. “I’ve gotten hung up on many a time,” Dr. Krys Johnson, an assistant professor in Temple University’s department of epidemiology and biostatistics, tells Mental Floss.

Some simply aren’t willing to accept that they might have been exposed to a disease without knowing it. After several employees at a certain company tested positive for COVID-19, for example, Perramant started calling the rest of the workers to tell them to go into quarantine; this way, she could prevent sick people who weren't yet showing symptoms from spreading the disease without knowing it. But not everybody was open to her advice. “They would just swear up and down, ‘I haven’t been in touch with anybody who’s positive, please don’t call me again,’” Perramant says.

But there are plenty of cooperative people, too, especially victims of foodborne or diarrheal illnesses. “They really want to know where they got sick because they’re so miserable that they never, ever want to deal with that again,” Johnson explains. Parents of sick kids are also generally forthcoming, since they want to keep their kids healthy in the future. And then there are those who don’t have any problem spilling their secrets to a stranger.

“There was one woman who was very memorable,” Johnson says. “I called her about her Hepatitis C, and she was like, ‘Oh, honey, I did drugs back in the ’80s. That’s where I got my Hepatitis C. I pop positive every time!’”

4. Epidemiologists deal with a lot of rejection.

Public health epidemiologists have to learn to just shrug off all the rude tones and dial tones, and epidemiologists in academic settings need thick skin for different reasons.

“There’s just a lot of rejection,” McCullough says. “‘That idea isn’t good enough; this paper isn’t good enough; you’re not good enough.’ That is just a resounding thing. There’s a high bar for science; there’s a high bar for federal funding; and it takes a lot to cross that bar. So in the academic setting at these top-tier institutions, you really just have to have a thick skin.”

5. Just because epidemiologists' guidelines change doesn't mean they're wrong.

Sometimes, McCullough explains, the story of a disease can change over the course of one study. When you look at the first 100 people in a 10,000-person study, you’ll see one story emerge. By the time you’ve seen 1000 people, that story looks different. And after you’ve seen the data from all 10,000 people, the original story might not be accurate at all.

Usually, epidemiologists can complete the whole study of a disease and draw conclusions without the world clamoring for half-baked answers. But with a brand-new, highly infectious disease like COVID-19, epidemiologists don’t have that luxury. As they’ve learned more about how the pathogens spread, how long they can survive on surfaces, and other factors, they’ve changed their recommendations for safety precautions. Everyone else in the world of epidemiology expected this to happen, but the general public did not.

“If we say something this week that contradicts what we said last week, it’s not that we were wrong,” Johnson says. “It’s that we learned something between those two time points.”

6. Being an epidemiologist would be easier if people kept better track of their behavior.

Often, people omit vital information about how they got exposed to an illness because they just don’t remember all the details. You could easily recall devouring a few slices of the decadent chocolate cake your mom baked for your birthday last Friday, but you might not be able to name every bite of food you ate on a random Thursday three weeks ago.

“People aren’t telling us the whole truth, but it’s not that they’re being intentionally obtuse,” Johnson explains. “With recall bias, unless there’s a reason for us to really remember, we’re not going to remember everything we actually ate.”

This has made it especially difficult to trace an aerosolized disease like COVID-19.

“All my friends going into the Fourth of July were like, ‘Should we have a get-together?’” Perramant says. “And I said, ‘You can have people over, but you better take an attendance list. You better have a little spreadsheet on Google Drive that has every person’s name and their phone number, so that when one person tests positive and gets sick this week, when I call you, you will be able to give me that information like that.’”

7. Epidemiologists have reason to be wary of buffets, cruise ships, mayonnaise, and cubed ham.

Infectious disease epidemiologists may have accepted that germs are a part of life, but they also know where those germs like to congregate.

“I don’t go to buffets, I have never been on a cruise ship and I don’t intend to, I’m super conscientious when I fly,” Johnson says. “And I’m really aware of whenever mayonnaise-based things are put out at family functions. If you’re ever at a potluck and people come down sick, the first thing people say [they ate] is potato salad or egg salad, because mayonnaise can spoil so quickly.”

“[Cubed ham] is one particular microbe’s very favorite thing to multiply on, so if you’re gonna have ham, make it a whole ham,” she says.

8. Teaching people is a really rewarding part of being an epidemiologist.

In addition to actually leading lectures in the classroom, academic epidemiologists also work extremely closely with their students on research projects; McCullough estimates that she’s in contact with hers at least once a day when they’re collaborating on a study.

“To work with someone so closely, and to watch them progress as a scientist and as a person, and then to have to let them go and send them out into the world, I find that very rewarding,” McCullough says of her trainees. “As a scientist in an academic institution, there’s not a whole lot of immediate gratification. Our papers get rejected, our grants don’t get funded, but the trainees are always a source of immediate gratification for me, so I hold them close to my heart.”

Epidemiologists in other spheres have teaching opportunities, too. When a community experiences a disease outbreak, public health epidemiologists like Perramant are responsible for helping the general public understand what they can do to prevent the spread.

“I like to teach kids about infectious disease and infection prevention for what’s relevant to them. We’ve had a couple of large outbreaks at summer camps, and last summer I put together a training for camp counselors,” Perramant says. “That’s always a part of my job that I really love.”

9. Epidemiologists have a unique understanding of racial disparities.

At this point, it's exceptionally clear that COVID-19 is disproportionately affecting people of color in the U.S. They're more likely to be exposed to it, they have less access to testing, and the preexisting conditions that place them at a higher risk can be the result of systemic racism. When these trends started to become apparent, McCullough got flooded with phone calls asking why. Her answer? This isn’t new. As she’s seen in her work as a breast cancer researcher, Black women are more likely to die of that disease than their white counterparts, and similar health disparities exist across the board.

McCullough explains that the general public is finally realizing what epidemiologists already knew: That poor disease outcomes in minority, low-income, and rural populations aren’t because of anything those people are doing on an individual level. Instead, it’s a result of systemic issues that keep them from leading financially comfortable, healthy lifestyles with access to healthcare and other resources.

“It’s not just COVID—it’s almost every single chronic and infection ailment that’s out there,” McCullough explains. “So this is a real opportunity for people to step back and take an assessment of where we are in terms of our healthcare system, and what we’re doing so that everybody has equitable outcomes. Because people shouldn’t die just because they live in a rural area, or just because they’re poor, or just because they’re Black or Hispanic.”

10. They've had to deal with a lot of “armchair epidemiologists” lately.

Until this year, epidemiologists had to suffer through people mistaking them for dermatologists. Now, during the coronavirus pandemic, people finally know at least a little about their jobs. In fact, people are so confident in their newfound epidemiological knowledge that many are fancying themselves experts on the subject.

“At the beginning of 2020, there were like 500 epidemiologists, and now there are about 5 million. Everybody thinks they’re an epidemiologist,” McCullough says. “There’s a science to it, and it’s a science that requires training. We went to school for a really long time to be doctorally trained epidemiologists.”

It’s not just about advanced degrees, either. Beyond that, you need years of firsthand experience to grasp all the nuances of understanding methods, interpreting data, translating your findings into recommendations for the general public, and so much more. In short, you can’t just decide you’re an epidemiologist.

Perramant has her own analogy for the recent influx of self-proclaimed epidemiologists: “It’s like armchair psychology. Poolside epidemiology now is a thing.”
