The Keto diet isn’t the only thing Jillian Michaels isn’t a huge fan of.

The 44-year-old, who recently hit headlines after slamming the high-protein, low-carb dieting craze, said she also has a dislike for CrossFit.

She explained in a video posted by Shape, “My issues with CrossFit are as follows. First of all, you’ve got what — 20 to 25 movements that don’t really vary? And you’re doing them over and over and over again.”

“So on one hand it stops being effective because you’re not challenging the body from various angles of push and pull, with different varieties of exercises and different types of movements that work different modalities.”

She continued, “And I know CrossFit [athletes say] — ‘Oh, we work all the modalities!’ — but no, not really, so shouldn’t you choose a workout that has a little bit more flexibility and strength so you get more mobility, not just power, which is speed and strength.”

Instead, Michaels advised: “A little agility work, maybe some endurance training. So that you’re training in a more balanced way, to keep the body changing and keep your training more holistic by hitting all modalities of fitness.”

The fitness guru also said people would be “p**sed off” because she’s not a lover of skipping either.

She went on, “In case you aren’t familiar, it’s likely you’ve seen it in CrossFit. It’s when you use momentum by bucking or jerking your hips. And a lot of athletes or CrossFitters use this to do things like pull-ups or toes to bar. And they feel like it makes them more efficient because they can do more reps. Some believe it helps builds power which is speed and strength together.”

“Where I come from that’s called cheating, using momentum to do a repetition. And if you don’t have fantastic form, you can get hurt, and we don’t want that to happen.”
