Why Jillian Michaels Doesn't Think You Should Do CrossFit

From Prevention

Jillian Michaels has been very outspoken lately. First, she called the keto diet straight-up bad because it stresses eating only fat and protein. Now, she's taking on another health trend with a cult-like following: CrossFit.

In an article and accompanying video on Shape, Michaels explains her main beef with CrossFit. The story was published in December and has recently resurfaced online. She faults the sport for not being varied enough to provide a balanced workout.

"You've got like, what, maybe 20-25 movements that don't really vary? And you're doing them over, and over, and over again," she says in the video.

According to Michaels, the structure of the workouts don't keep your body challenged. She believes you need to incorporate exercises that improve endurance, agility, and flexibility, which she claims CrossFit lacks. Instead, she says the popular trend focuses mainly on speed and strength.

But above all, there's one thing Michaels truly hates: kipping. For those who don't know, kipping is a variation of the pullup that uses momentum to help you lift your chin above the bar. In the article, Michaels writes she doesn't understand why some would choose to perform a kip rather than the strict version of the movement, which uses your body's entire range of motion.

So, what's the main reason you should avoid kipping? "Injury. Injury. Injury," writes Michaels.

"One can argue that with a good base of athleticism and proper form, these injuries can be avoided," she explains. "But I say the forces on the shoulder and lower spine are extremely high during kipping movements, so the risk is there for even seasoned athletes."

Michaels resurrects a long-debated topic as fitness pros have been arguing whether or not kipping is actually beneficial. As Men's Health previously reported, kipping pullups put pressure on your lower back and shoulders, and isn't a good fit for about 95 percent of the population.

However, CrossFit likely won't take a hit from the criticism. If you want to give it a shot, and stay safe, check out Men's Health's beginner's guide to CrossFit.
