Check out my Plyo Routine v1. Start priming your stretch shortening cycle – the rate at which you’re able to relax then contract your muscles and tendons to react and reabsorb the force you put into the ground back into your body.
Plyometrics isn’t just about jumping up and down. You can either jump with force or jump with low impact. Jumps and landings can explosive or they can be gooey. If your tendons are gooey, and react slow to the ground impact, all the force will dissipate out and you’ll lose most of the energy you’re putting into the ground. If your tendons have good viscoelastic properties and are able to stiffen at point of impact then they will be able to reabsorb the force you put into the ground back up into your body. You need to practice jumping with explosiveness and not just jump up and down for the sake of jumping. Prime your body to explode your body into the air and drive force into the ground when you land so you can redirect that force back into your body to jump higher.
Please be advised, this routine isn’t for beginners. If you’re still starting out, I’m working on the Spriint Fit routine for beginners, so stay tuned for that, also check out my Squat Progressions to help get you primed and build foundational strength.
