HOW: Start with your hands supported on an elevated surface like a couch or bench behind you at your sides. With your hips unsupported in the air, but your feet supported on the ground, lower your hips down towards the ground by letting your elbows bend and shoulders shrug. Lower down as far as you feel comfortable with, then press through your hands to straighten your elbows and return to starting position. Repeat
FEEL: This should feel like an upper body workout, specifically your triceps, shoulders, and shoulder blades. The closer your feet are to you, the easier the exercise is.
COMPENSATION: Try to keep your upper torso still in terms of not leaning back or forward excessively. Move slow and controlled, think time under tension is better here than speed. Be mindful of your elbow flare, try to keep your elbows tucked back as long as it feels comfortable for you.
