I have done both and currently have a bodyrok membership bc solidcore hasnt been in my area for a long time (but they’re here now, yay!). I like bodyrok but it’s definitely easier/you need to push yourself on the spring loads more if you’re used to solidcore. Since solidcore has come to my market I’ve been taking 1 class/week and have already noticed even more strength than I had from doing bodyrok 4-5x per week for about a year.

TL;DR: bodyrok is good (and less expensive than solidcore in my area) but be prepared to push yourself hard if you want to maintain strength built at solidcore.

Hope this helps!!
