The side plank is an exercise common in pilates and yoga. It primarily targets the obliques and to a lesser degree also targets the abs and glutes.
Lie down on your left side on an exercise mat. Place your feet together on top of each other. Next, place your left hand on the mat under your left shoulder.
Begin exercise by pressing into your hand and raising your hips so that your body forms a straight line from your ankles to your shoulders. Place your right hand on your right hip or raise it straight up in the air.
Hold this position for desired amount of time. Lower down and repeat on right side.
If you have weak or painful wrists rest on your elbow and forearm. To reduce the resistance and make the exercise less intense rest on either one or two bent knees.
