Lie on your front with your hands directly under your shoulders, and the balls of your feet in contact with the floor.
Keep your back straight and engage your abdominal muscles throughout this exercise to prevent your back from sagging.
Push your body upwards by straightening your arms, ensuring you do not lock your elbows at the top of the movement.
Pause briefly and then lower back down in a controlled manner until your chest touches the floor.
Your elbows should remain close beside your body.
Momentarily take your hands off of the floor, and then repeat.
