How do you do a plank?

To properly perform a plank, get into a push-up position, and rest your weight on your forearms. Planking is a great abdominal workout.

1. Get in a push-up position

   Lie on the floor on your stomach. Assume the push-up position by moving your weight onto your hands and feet.

2. Shift your weight to your forearms

   One at a time, shift your weight off your hands and bend your arms until they are parallel to the floor. Position your elbows directly under your shoulders and shift your weight onto your forearms.

3. Hold the plank

   To get the full benefits of this exercise position, hold the plank for at least 30 seconds.
