Want to pump iron while still maintaining your geek cred? The newest fitness collection from Onnit is the surest way for a Star Wars superfan to get swole.

Onnit, which describes itself as a maker of supplements, health foods, and "unconventional training equipment," lives up to its promise by delivering a line of kettlebells featuring iconic Star Wars characters. There's a 50-pound Boba Fett version, a 60-pound Stormtrooper version, and naturally, the heaviest kettlebell at 70 pounds has been reserved for Darth Vader himself. Priced between $150 and $200 depending on the weight, the kettlebells have been sculpted and cast in chip-resistant iron.

Most importantly, it's fully functional. Just check out the video below to see the kettlebells being used in a series of deadlifts, squats, and other strengthening exercises.

There's also a 20-pound Death Star slam ball ($75), which is a little like a medicine ball except it's designed to withstand the impact of being thrown, dropped, and hurled against hard surfaces. It's made of durable polyurethane rubber and has ridges along it to help you grip the ball better.

For those who prefer something a little less intense, Onnit also designed a reversible yoga mat for $65. While you're in downward-facing dog, you can align your hands with those of Han Solo, who appears to be frozen in carbonite (and also apparently trapped in your yoga mat).
