Movement:
Stand with your feet on either side of the step. Squat down and as you return to the starting position jump up, landing with both feet on the step, carefully jump down and perform a squat, repeat movement for reps or X-amount of time.
Always remember quality is better than quantity. Be in control of the weight, the weight should not control you. Make every rep count.
Always be sure to give your best, then no one can say anything about you.
