Instructions
Stand strong, with your feet grounded and placed shoulder-width apart while maintaining a tight core and flat back.
Fully extend one arm directly out in front of you and rotate it so that the palm is facing down.
With your free hand, take hold of the back of your outstretched hand and gently pull it down towards the floor.
Keeping your arm outstretched, you should feel a light stretching sensation in your wrist and upper forearm.
Hold this stretch for the specified amount of time.
