Set up a bar at waist height or use a suspension trainer. Stand facing the bar or suspension trainer, with your feet shoulder-width apart. Grab the bar or handles with an overhand grip, slightly wider than shoulder-width apart. Lean back, keeping your body straight and your heels on the ground. Pull your chest towards the bar or handles, squeezing your shoulder blades together. Pause for a moment at the top, then slowly lower yourself back to the starting position. Repeat for the desired number of repetitions.
