Runner’s Lunge to Explosive Step Up- Begin facing the Reebok Step.  Step back into a lunge with your left leg.  Powerfully press into the floor with your front foot, engaging your right hip muscles to explode up.  Drive your left knee up, stepping onto the Reebok Step with your left foot.  Continue the sequence with a hop on the left foot, driving the right knee up towards your chest.  Come down with control and repeat on that same side for 30 seconds.  Now perform the movements on the other side (beginning with a right lunge back) for 30 seconds.

Decline Plank Jacks- Set up in a tall plank position, feet on the Reebok Step and hands placed on the floor directly under your shoulders.  Maintaining stiffness through your core  and keeping shoulders over hands,  jump your feet off and back on to the Reebok Step in a “Jacks” pattern.  Continue for 30 seconds.
