Begin by standing tall with feet shoulder width apart. Bend over from the hips and touch the floor with your palms flat on the floor. Keep your legs straight as you walk your hands as far forward as you can until you are in a high plank position. Keep your core braced throughout and do not let your hips drop. Lower your chest towards the ground by bending your elbows until your chest is just above the ground or you feel a stretching of your chest and shoulders. Hold for a count of one then press upwards from your chest and shoulders, straightening your arms as you return to the high plank position. Then return to the standing by moving your hands back towards you feet until you can once again stand tall. Continue for the required number of reps (or time).
