Lower the weight quickly to about an inch off the chest. In this position to maintain, and hold the weight there you will have to be unbelievably tight. Once it’s there, pause for a split second.
Press the bar about 2/3 through the lift, and then let the bar lower. By pressing this far you are maximizing lat, pec, and delt recruitment without hitting the triceps just yet.
As the bar lowers a second time you want to pause, just as before, about one inch off the chest. Then with all your strength you want to explode the weight to the top. Completion of this cycle constitutes one “rep”.
You want to pick a weight that is challenging to get for 6-8 reps. I have found that 60-70% for 2-3 sets is very taxing, but still allows for maximum recovery, yielding the best result.
