The rowing ergometer favors the rower of greater mass. This little program will compute mass adjusted times at any distance. It turns out that a 7:00/ 2K @ 200lbs is about equal to a 7:30 2K @ 150 lbs!
Good pull-ups are led with the chest. Notice Greg Amundson’s arms are nearly perpendicular to the chest as in a rowing motion. This incorporates critical muscles of the upper back. This posture is indispensable to high rep pull-ups.
