PULL YOUR OWN GROIN Groin injuries are very common, and this simple little exercise is great preventive medicine. Stand with your feet about twenty-four inches apart. Gradually transfer your weight over to your right foot (without moving either foot). As you do this flex your right knee (it will move slightly forward) so you can accommodate the weight transfer. Keep your left foot solidly on the ground and your leg straight. You’ll start to feel a pull in your left groin. Gradually move into it and stretch. Hold it for ten seconds. Then do the same movement for the other leg.
