The negative pushup focuses on the eccentric phase of the movement to build the necessary strength for a full pushup. Start in a high plank position with your hands slightly wider than shoulder-width and your body in a straight line. Slowly lower yourself towards the floor by bending your elbows, aiming for a count of 3 to 5 seconds. Keep your core tight and ensure your hips do not sag. Once your chest touches the ground, place your knees down to push yourself back up to the starting position or simply reset.
