Begin by lying on your side with your elbow directly under your shoulder and your knees bent at a 90-degree angle. Place your top foot on a bench or sturdy surface.

Engage your core and lift your hips off the ground, forming a straight line from your head to your knees. Keep your bottom leg bent and parallel to the floor.

Hold this position while maintaining tension in your core and glutes, then slowly lower your hips back down to the starting position. Repeat for the desired number of reps before switching sides.
