Stand facing a wall and place a ball between your forearm and the wall.
Your hand should be pointing upwards with the thumb pointing behind you.
In your other hand hold a small weight with your arm by your side.
Take a step forwards, with either leg, and at the same time roll the ball upwards under your forearm.
Roll the ball only as far up as comfortable.
Return to the start position, and repeat.
When ready to progress this exercise, stop in the top position and lift the weight in your other arm from your side as high as you are able, with your thumb pointing behind you.
Return to the starting position.
