I can happily do pistols on one leg, while on the other I just keep falling on my ass when I reach the bottom position.
I am working my mobility since almost two years now with little success.
Tried everything: foam and ball rolling on foot and calf, stretching, mobility exercises with band distraction, and voodoo floss.
Keeping falling on my ass unless I carry a weight in my hands to counterbalance the weight. So frustrating.
