I'm cold cartoon David Taylor. I'm in the garage to show you pull-ups on the timer. This time reverse grip. The idea see as many pull-ups as you can in the allotted time. The timer set for you, so get on the bar and we're going to go reverse grip. And when the timer goes. We begin. Pull-ups quickly. And is cleanly. As possible. Until the timer runs out. That's put on the timer reversion.
