Bring yourself to the ground and enter a high plank position with your hands directly under your shoulders. This is your start position. Keeping you core braced, lower your chest towards the ground by bending your elbows until your chest touches the ground. Inhale as you do so. You should maintain an unbroken line from your head to yours toes throughout this lowering phase. At the bottom of the movement, when your chest touches the floor, gently lift both hands just slightly off the floor. Immediately return them to the floor and then press upwards from your chest and shoulders, straightening your arms as you return to the high plank position. Exhale as you do so. Repeat for the required number of reps (or time).Ce
