Tip #8: Waveloading. Here is another good instant vert. Trick you can play on the nervous system. Load your body with some weight before jumping, like say jumping with a medicineball. What happens is your body will recruit more motor units in the working muscles, allowing the work to seem much easier when you don't have the weight because you are now using more of them! This trick works with any exercise & is great for breaking plateaus.Another variable to this method is what i call an "unloading jump". To perform this all you need to do is grab a pair of 10lb dumbells(or any weight) hold them at waist level, quick step up to the rim to do a rim jump (counter movement jump) at the peak of crouch just before you'd take off for the rim drop the weights and blast off. The science behind this methods is that when you load the eccentric contraction with more weight than the concentric (jump) you will be able to create more force.One set of 5-10 reps with this new drill will give instant as well as residual leap increases!
