Lie on the floor on the right side of your body. Position your elbow directly under your shoulder. Raise your body until it forms a straight line. Hold this position while you maintain a drawn in core and contracted glutes. Perform the side plank on the left side. Basic progressions: Side Plank with Arm Abduction- Same movement as above, except you extend your top arm up toward the ceiling gazing at the fingertips. Repeat on the other side. Side Plank with Arm/Leg Abduction- For more of a challenge, lift your top leg up towards your extended arm and hold this position as long as possible. Repeat on the other side.
