1. Single Leg Hip lift - We use the tennis ball to get active hip flexion on the opposite side thus locking down the lumbar spine so you can't use your back as your glute. Toe up so that you can't use your calf as your glute. 2. Half kneeling KB Chop/Lift - the half kneeling position is an upright single leg hip lift. The chop & lift adds a reaching component that the brain & nervous system crave. 3. Goblet Split Squat - now we're turning that half kneeling position into a resistance exercise. 4. Two KB/DB Walking Lunge - walking lunges are far along in the progression because you've added a decelerative & accelerative component to the exercise. 5. Single Leg Hop - the landing position for a single leg hop is a single leg hip lift standing up. Can't single leg hip lift with a glute that works well on the ground? It will probably be difficult to accept the ground well on a hop.
