Extend one arm in front of you at shoulder height. Turn your palm away from your body and point your fingers down.
Using your other hand, gently pull the base of your fingers back towards your body. Hold for 30 seconds before switching sides.
Then, extend your right arm in front of you at shoulder height, with your palm facing your body. Place the opposite hand on the back of the right hand. Push the right hand into the opposing hand to feel a stretch in your forearm.
