Anyway Its normal I think
If your muscles hurt it usually means they're being worked and overtime will mean they're going to build up. If you're doing it so much that they continue to hurt and get over the top bad then have a rest, don't do as much and let your muscles settle down so they don't hurt.
Not good.
Always stretch, stretch, stretch, stretch
Always stretch, stretch, stretch, stretch
