Lie on side on exercise mat with legs extended and stacked on each other. Position elbow directly under shoulder, with forearm resting on the mat perpendicular to body. Engage core by pulling navel towards spine, press forearm firmly into the mat. Lift hips off mat, creating a straight line from head to 1heels.

The Basic Side Plank Form: To do the Side Plank, start lying on your side with your top leg in front of your bottom leg, propped up on your elbow with your elbow under your shoulder. Rest on the inside of your front foot and outside of your back foot and then flex your feet as you lift up.

With proper form, side planks can help you build a strong core. They work the oblique muscles on the side of your abdomen more than standard sit-ups or crunches. Perform side planks by balancing on your side with your elbow directly under your shoulder, touching the floor with your forearm and the side of your foot.
