Stand holding a kettlebell in one hand with you elbow straight and arm by your side.
Place one foot in front of the other so that the heel touches the toes of your other foot.
At the same time swing the kettlebell forwards.
Then let the kettlebell swing back while you take a step forwards using the other leg.
Again place your heel close to the toes.
Keep your balance and hips facing straight forwards during the exercise.
Repeat using your other hand.
