HOW: Set up an elevated surface that you will lean onto. The lower the surface the more challenging the plank will be. Place your elbow on the surface and make sure your feet, hips, and shoulders are in line with each other. Lift your bottom leg off of the ground, hold the plank position with your top leg and core muscles.
FEEL: You should feel your inner thigh muscles on the top leg and core working.
COMPENSATION: Don’t let your hips drop, keep everything in line with each other.
