Focus on getting the triceps pumped to hell with these, to the tune of 4 sets of 15-20 reps.
You want a smooth transition from the pullover into the press part. No pausing at any point. We want to let the metabolites really accumulate and focus on creating significant metabolic stress, which is why the rest period between sets is only 60 seconds.
For this mechanical drop set, you'll start with the hardest exercise and, as you fatigue, move to the easiest. Works with a bar and a supinated grip too.
