Today, focus on power and making the concentric portion of each movement as explosive as possible. Since explosiveness is the main objective, you'll be using a lower weight—starting with bodyweight jump squats and then using fifty percent of your 1-rep max or your 25-rep max for dumbbell presses, close-grip bench, and rows. You might be asking yourself, "What is my 25-rep max?"
If you aren't sure what weight to begin with, aim to use about half as much weight as you typically do. It might be a bit of an ego hit, but remember—picking up a lighter set of dumbbells allows you to focus on explosiveness rather than simply lifting as much as possible. You're not trying to train to failure, but you are trying to make each and every movement count.
