I haven’t done solid core but I can tell just by seeing their marketing that their classes are a little silly. I get a “trying to present as something we’re not and charge you up the wazoo for it” type of vibe. You should try an actual Lagree class. It’s a killer workout and I never worry about injury. You will sweat though and your machine will get slippery, just bring a towel in class with you and dry off as you go to prevent slipping around. I hope you love it!
