Test your shouldersliterally. From a plank position, you'll use each hand to tap the back of the other, alternating at top speed. Keep count as you go, and try to beat your own record. Your first attempt is a baseline; improve on it with practice.
Take up a push-up, or plank, position on the floor. Your weight will be on your hands and toes, with your back flat and a straight line from the top of your head to your heels. Place your hands wider than your shoulders, about 3 feet apart (see Photo 1).
- From the starting position, quickly bring your right hand across to tap the back of your left hand. Returning your right hand to the floor, immediately do the same with your left hand, bringing it across to tap the back of your right hand. As you do this, keep your plank position strong and flat, with your shoulders and hips parallel to the floor (see Photos 2 to 4).
- Continue to alternate taps, as rapidly as possible, for 60 seconds. Keep count as you go, so that you can try to increase your number each time you do this exercise.
