Back, Core, Shoulders, Latissimus
Place both hands on a pull-up bar with your palms facing away from you. Stand on a box or thick mat if you need help reaching the bar.
Jump up so your chin is above the bar and tuck your knees. Keep your core tight, and focus on engaging your back muscles, keeping your shoulders pressed down away from your ears.
Hold for the required amount of time.
