If you look at guys like Gilbert Arenas, LeBron James, or even Michael Vick, you'll see that when they run/sprint, it seems very effortless. When they sprint full speed, it's like they just float above the surface. And when they run/jog, they kind of bounce of the ground. Hard to describe, you have to see it.
My question is, what is it that makes them run/sprint like this? Is it strength, technique, flexibility? And is it achievable through practice?
Because there are guys who are fast, but don't really look as effortless whey they run, e.g. Tracy McGrady (not to take anything away from him).
My technique isn't really great and I'd like to improve it.
I might be posting on the wrong board, but I hope there someone who has some opinions on this.
