One of my FAVORITE drills to work on leg drive and the launch off the rubber: the NO ARM reach and freeze drill So many pitchers struggle with the launch off the rubber. Especially pitchers with very big backswings or a lot of arm movement in their load When I see excessive backswings in a pre-motion, it tells me that the pitcher is very upper body oriented. Meaning, they’re trying to create their momentum off the rubber by swinging their arms and using upper body instead of using hips and legs
