While standing in a position like this
I want to be able to jump off the ground easily with one foot). Normal squats don't work well for this kind of a movement. Pistol squat is a better practice, but to do that you have to have a certain strength. Though, I can do it while holding the wall and that will be my choice if I don't find any better workouts. So what other types of workouts can I do to increase this strength?
