Second day? You just got started, so it's not going to be fun. After a while though, you'll just get used to it and all that practice stuff will be easy. And if you want to be healthy and strong, keep it up. Maybe you can't do that much at the beginning, but you'll get stronger and better as you go. Keep at it, and you'll be fine.

Unless you want to quit. Seems like you're not enjoying it that much anyway (from your other posts)....
