A woman has gone viral on TikTok for her dance style workouts that she posts, including one about a thrusting motion that she says will give you flat abs if you do it for 5 minutes a day for one month. However, some fitness experts say it could be really dangerous.
According to Yahoo:
Morit Summers, personal trainer and founder of Form Fitness Brooklyn, describes the move as a "very aggressive hip thrust" that could be dangerous, especially to the lower back.
"I actually think that if you do that too much you could potentially cause some real spinal and nerve pain," she said. "I would just want people to be careful and maybe change it up a little bit."
Erin Schirack, fitness instructor and co-founder of streaming fitness platform CHI-SOCIETY, says there is some validity in the sense of the move itself, which she describes as a "pelvic tuck," which can "help loosen up the lower back and find engagement in the lower abs."
The way it's done in this viral class, she says, is not proper form.
"That format is so wild and out of control that it causes it to actually be completely ineffective," she said. "(It's) not done in a safe manner."
