#3. Single-leg hip raise
While lying flat on your back, place feet approximately hip width apart and flat on the floor allowing for a bend in the knee. Bring on leg off the ground and straighten it. From here, engage the core muscles and press through the heel to drive the hips upwards away from the floor. At the peak of the movement squeeze the glutes and hold, making sure to keep the core engaged! Return to the ground and alternate to the other side.
