Stride

Many young pitchers fail to keep their weight back when striding toward home plate. They often start with their weight forward before their leg lift is complete and they often loop their front foot toward the plate in a way that shifts their weight forward too quickly.

Young pitchers should consider adopting an "up-down-out" movement with their lead leg. The knee comes straight up (to the point where they can balance themselves), and then goes straight down within a few inches of the ground, and then slides above the ground toward home plate until the stride is complete.
