Tested my Vert today after a full cycle of the athlete‘s strength programm and it went up by 2 Inches

I've been working with the Athletes Strength program for a few weeks now and am already seeing pretty good progress.

What is going on guys! Today I posted a video on my IG about using fast eccentric lifts. As your strenght levels go up, this is a very intersting way to start training your ability to produce force fast in both directions of the movement. I am intersted to hear how you guys like these lifts and if any of you have tried them before?
