This is a tricep workout that myself and Vince DelMonte did while working out on vacation in Las Vegas. The small hotel gym we were training at had a limited amount of equipment (i.e. an adjustable bench, dumbbell rack, and some resistance machines). So this entire tricep workout is done using just dumbbell exercises only.
We used the Positions Of Flexion style of training which starts with a mid-range compound exercise (rolling db extensions), then goes into a fully streched exercise (overhead db extenstions), and finishes up with a peak contraction exercise (db tricep kick backs).
