JK: had to look up reverse clamshells - they look very uncomfortable. I don’t even like normal (banded) clamshells too much, but they seem to help. How do you manage bridges with limited flex on one knee? My PT also has me do unilateral - one legged - bridges, and those are challenging. If you find an exercise for the hip problem that trumps all others, please let me know. My hip is much improved (without shot), but it can always be better.
