Very frequently we start our training sessions at TSS with some basic jumping. It should not be overlooked or underestimated. I do not like jumping for conditioning very often, as you will see in the video how it can diminish performance. Try to keep your feet moving fast and explosive. Know the difference between power and conditioning and when to use both. If you choose to do sets of 20 or more short box jumps in a circuit, that's fine, but it's just not my style. It will burn calories, and build endurance, but it will do little for building power and speed, in my opinion. Here are a few options and suggestions for incorporating jumping into your training, preferably before some heavy lifting.
