I'm not in a league, and have no idea how fast I throw. That said, I do throw often. I'm primarily working on long tosses now to strenghten my arm. I'm starting to find that my front leg is very ... weak. Actually, both legs are weak. How did I figure this? Well, when I threw I felt as if I'm not stable. I can throw the ball far, but I'm landing all sorts of ways. A few weeks ago I started running more than throwing. Exercising my legs helps out a ton with my velocity. Well, I'm throwing much farther now.
How does this translate to this topic? Well, when I throw and land my front leg, I tend to put more pressure on it. Basically, it's more of a stomping through motion than placing my foot down. I'm using my leg to apply force to the ground, which then transfers more energy to my arm to whip that ball a long distance.
What I'm trying to get at is that since my legs are much stronger, I'm able to explode my hips in such a way that it feels like I'm stomping through the ground. In reality, I'm just moving my lower body with more force.
So ya, exercising the legs and visualzing stomping through the ground helps me a lot. I'm not sure if anyone agrees, but this is the way I can make this explosion work for me :oops: .
