Chris, on one of your current Kerr talk videos you mentioned that you had purchased several of the toepro devices from human locomotion. Have you started to integrate those with your sprinters? If so, is that a daily exercise?

Chris, On your Kerr talks, TORSO pt.1, you mention about motors. I'm assuming these are what you are talking about: https://www.humanlocomotion.com/products/focal-vibration-motors/ I've used these with the prescribed workout for the Quads, Hamstrings, Peroneal, and Calves. I've found that if you are able to keep up with the 1x month maintenance protocol grumpy hamstrings and calves have disappeared in my kids. I'm wondering if you have experimented with any other muscle groups like oblique's, adductors, QLs, or glutes.
