Hold each end of a long resistance band in your hands. Place both feet onto the middle of a resistance band and stand with them just wider than shoulder width apart. Stand tall, brace your core and avoid arching your back. Your arms should be extended in front of you, just in front of your thighs with your palms facing in. This is your start position. Brace your core, keep a neutral spine and look straight ahead as you pull your hands up to directly under your chin, keeping them close to your body throughout. Exhale as you do so. Pause at the top of the movement, then slowly lower your arms back to the start position, inhaling as you do so. Repeat for the required number of reps (or time).
