Place your top leg on top of the bench, bent at a 90-degree angle so your knee and lower leg are supported.
Position your bottom forearm on the floor directly beneath your shoulder.

Keep your bottom leg tucked under or resting comfortably.
Hold this elevated position, focusing on squeezing the inner thigh of the top leg against the bench.
Keep your hips square to the front and avoid sagging through the shoulder or lower back.
