Put your wrists underneath your shoulders, knees close to wrists. Protract and depress as much as possible (Sternum up and shoulders back). Externally rotate your elbows so the creases face forward, squeeze inwards to the floor to activate your chest. Compress your core. Keep knees really close to the floor but not touching. Lean as far forward as you can but only as long as you maintain a perfect form. slight bend in the elbows, scapula relaxing or core opening will count as a repetition failed.
