I don't think I'm dehydrated per se, but I could probably stand to to drink more. And if this was just minor soreness, I'd attribute it to something like that, but there have been a few instances where I could barely move for several days after a workout with my trainer. Granted, I'm worked muscles in novel ways with him at times, but even with that, the soreness seems extreme. Maybe I'm just way more out of shape than I realize. That is a distinct possibility.
