Place a resistance loop around your wrists. Move down into the prone position with your hands directly underneath your shoulders with your toes and balls of your feet in contact with the floor.
Push upwards extending your arms out straight but 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 is just off the floor.
Keep your back straight and engage your abdominal muscles throughout the exercise to prevent your trunk from sagging.
