I have recently conquered deck squats with the integrated mobility, so this last week I've been working on cossack squats. I don't have any problems with cossack squats. The integrated mobility (twisting squats) isn't much of a problem either, but the twisting motion is really hard on my heels because I train barefoot. I've tried the carpet in my basement and the concrete, but both seem to chafe my feet. Have you guys found a solution to performing the integrated mobility without pain?
Thanks
