WHY: This exercise is great for working the side muscles. This includes your shoulder, core, and hip muscles that are closest to the floor.
HOW: Lay on one side with your forearm against the floor for this exercise. Lift your hips off of the floor to a height where your knee, hip, and shoulder are in one straight line. Make sure to avoid sagging at the hips here.
*If this exercise irritates your shoulder, you can side plank on an elevated surface. This will decrease the demand of the entire exercise*
FEEL: You should feel this exercise in your shoulder, core, and hip muscles that are closest to the floor.
