Joel Stubbs on Pullups:
“I like doing chins first and with different grips, because this really warms up the various back muscles and stretches them out. When I change my hand positions, I feel different muscles working in different ways. I feel more of my upper lats and rear delts working with the wide forward [overhand] grip. With the hammer [palms facing each other] grip, I feel more of the traps tying into the rhomboid area. With the reverse [underhand] grip, I feel more of my rhomboids and the lower part of the lats.”
