So I'm reading through the articles, and the stuff suggested here all looks very solid for improving my jumps (Parkour purposes). I don't however have access to a squat cage, or enough weight to do serious squats with my dumbbells. What's the best way to adapt the workouts with body-weight and a dumbbell set that's really only meant for upper body. Pistol squats, weighted split squats?
And if I'm doing dumbbell split squats, should I be doing 1 dumbbell in the rear hand, or a dumbbell in each hand, I see instructions for both.
