Mobility Exercise: Leg Drive Variation Combo

Holding the upward plank position - this is a super pre-workout core, hip and leg activator.
Engage the abs, start with knee drives across your body, bring your left knee to your right elbow whilst keeping the hips up. Return and repeat quickly with the opposite side while holding a strong body position for 10 repetitions.
Next keeping the strong upward plank position take the movement into long leg taps to the side alternating and repeating for 10 reps.
The last variation will be taking the movement into tucks under the body. Bend the knee and one leg at a time tuck each leg under the hips to feel a stretch though the glute and outside of the hip.
