As a kid I used to love swinging on the school yard swings. I’d try to see how high I could get myself to swing. Being young and in elementary school, I felt like I was super high.
Being quite the risk taker and wanting to have the feeling of flying, I’d jump off the swing at its highest point when recess ended. The momentum of the swing would launch me higher into the air and I’d come crashing down to the ground with extreme forces, landing with both legs.
I didn’t know it at the time, but this was one of my initial experiences with plyometrics and depth jumps.
