Jumping up and down

I’ve long believed in jarring the body with impact. Some of that is hitting, which also frees up motion in joints and across connected muscle chains, and some is literally jumping. I’ve done a few searches and can’t find anything intelligent about why this is good. It is, to me, the ability of the body to absorb impact shifted to your legs and core. It strengthens the joints and teaches the body how to align itself for ‘falls’ or other impacts. Remember, when you jump down, you decelerate when you hit the ground and that means you absorb not only your resting weight but the ‘weight’ added by gravity accelerating you down. I’ve also been doing more bunny hops up stairs, meaning jump both legs at the same time without hand assist – though sometimes with a guide hand touching a hand rail to make sure I don’t fall on my face. This is more ‘plyometric’, though to me the benefits are largely in getting the mind to recognize the efficient motions for jumping are essentially the same as a kettlebell swing, a deadlift hip snap, etc. I seem to be alone in this but I think there’s more value in jumping down because absorbing impact is more useful, as in you need to get away from something or need to get at something and that is more likely to require changes in elevation that include jumping down because you’ll actually tend to clamber up something instead of bunny hopping. I mean jumping down is efficient real world stuff, but bunny jump up is an exercise for a gym. This is why I practice stepping up and over obstacles, and stepping up and jumping off obstacles.
