Now that you've run through this routine once before, ramp it up and go hard with another set of pull-ups. They'll target your lats and traps, and create that coveted V-shape.
Maintain full range of motion and do your best. Can't hit that last set of pull-ups? Modify with the jumping or band-assisted version—just don't fall victim to sloppy form. Concentrate on contracting your lats as you flex your elbow, and avoid swinging or jerking movements. Remember to ease into each downward motion and keep that steady 2-1-1 tempo.
