Prevent golfers elbow

WHY IT HAPPENS: Consisting of a pain on the inner side of the elbow, which can spread into the forearm, this injury (also known as medial epicondylitis, fact fans) can occur from general overuse and technique errors such as a swing plane that's too flat.

HOW TO PREVENT IT: Dumb-bell wrist curls

Kneel with your forearms flat across a bench. Hold a pair of dumb-bells with your palms facing downwards and the backs of your wrists on the edge of the bench. Keeping a tight grip and your forearms still throughout, lower the dumbbells and then curl them up as high as possible.

Do two sets of 10 repetitions, then repeat with your palms facing upwards.
