Begin by placing your forearms on the floor and forming a plank with your feet and forearms.
STEP 2
Hold this position while keeping your body parallel to the floor for the prescribed time.
Special Notes
If you have problems with your lower back, this is not the exercise for you. This exercise is a great core strengthening exercise. You want to work up to the point where you can hold the plank position for more than 2 minutes. Once you can hold for more than a couple of minutes, it's safe to say that your core will be in pretty good shape. Make sure you place an exercise mat under your elbows and forearms. Doing it directly on the floor may be uncomfortable.
