Top Tip #2
Pullups should be done to the clavicle.
Yes its breatheren suggest only the chin need pass the bar, but that is only a partial rep. That last 4 inches of ROM makes the difference between hitting the back hard and not.
Add in that extra little bit of ROM and you will notice the difference!!
"But what about pulldowns?" I hear some say. All I have to say is, "Men do pullups and chinups. Are you a man or a mouse?!"
