Underhand Pull-Ups use a supinated (palms facing you) grip to emphasize the lats (latissimus dorsi) while engaging the biceps, traps (trapezius), and rhomboids (mid-back). Hang from a bar with your hands shoulder-width apart and palms facing toward you. Pull your body upward until your chin clears the bar, keeping your chest lifted and elbows close. Lower yourself under control to the starting position. This variation strengthens pulling power, arm muscles, and upper-back thickness, making it a versatile addition to any routine. Gymcheq helps you stay confident and precise with each rep.
