This workout is incredibly fun because you'll get to use even more training techniques than you may have in your usual routine. During this workout, you'll do dropsets and what's called "running the rack." After the last rep of the last set on an exercise that calls for you to run the rack, put down the dumbbells you were using and pick up the next-lightest pair. Do as many reps as you can, then put the weights down. Pick up the next-lightest pair and do as many reps as you can. Continue this pattern until you've gone down the entire rack.
During skullcrushers, you'll do what's called intraset stretching. During your last set, hold the contraction of the extended position for about five seconds, effectively stretching your triceps fibers under a heavy load. After such a brutal workout, this technique will set your triceps on fire!
