Set-up: Lie on your side with your top leg straight and resting on a bench or elevated surface, while your bottom leg hangs underneath, also straight. Support your upper body on your forearm, directly under your shoulder.
Movement: Lift your hips to align your body in a straight line, engaging your core and the inner thigh of the top leg. Maintain the position, keeping the lower leg relaxed or lightly hovering off the ground for added challenge.
Repetitions: Hold for the full prescribed time on one side, then switch sides and repeat. This counts as one set.
