Love both of these bodyweight back moves! And while often the inverted row will be used as a sub for pull ups, it does work your back in a different way and activate your back muscles to different extents than the pull up. The inverted row is a horizontal pull instead of a vertical one like the pull up. And focuses more on scapular retraction, your shoulder blades moving toward your spine, vs depression, your shoulder blades moving down toward your butt. | Redefining Strength
