Stand up straight facing a step and holding a weight in each hand.
Bend your elbows so that the weights rest just in front of your shoulders.
Place one leg on the step.
Ensuring your knee travels directly forwards over your toes, step up while simultaneously straightening your arms directly up towards the ceiling.
Bend your elevated leg through, bringing your knee up in front.
Keep your gaze ahead and your abdominals strong throughout.
Control the movement as you lower back down to the floor, leaving the same leg on the step.
Repeat this movement.
