Hi everybody, I want to pose a question about the service stance. I'm finding myself having more success when I stand on the balls of my feet, my heels well off of the ground, throughout the entire service motion. I mean from the time I line up my feet and start bouncing the ball until I explode up into the ball. I've been talking to people about this and I get a lot of different answers. Some keep the back foot planted throughout, some shift, raising toes and/or heels throughout the motion. Can I get comments on this? I have found that by having my heels never touching the ground my overall balance has improved considerably, and my upward explosion into the ball is more explosive and efficient. Thanks!
