Stand on the aerobic step platform with feet hip-width apart, holding a dumbbell in each hand at shoulder height with palms facing forward, torso upright and core engaged

Drive through the front heel and push off the step to return to standing position on the platform, extending hips and knees to stand upright, then alternate legs and repeat
