When training for a sport that includes a lot of single leg jumps (basketball, for example), how specific should the strength training be? Does strength training need to be single leg?
I see two ways of approaching this, and I'm not sure which is correct, or if I'm missing a third altogether:
Just get your basic two-leg barbell squat, deadlifts, power cleans as strong as possible. If your two-leg squat gets stronger, your one-leg squat gets stronger. No need for single-leg strength training.
Single leg strength work is important. Two-leg squats don't train the movement that's displayed in single-leg jumps.
I'm asking how specific the strength training needs to be. Of course, we practice single-leg jumps very often in plyometric routines, games, drills, etc.
