After five years of neglecting my body, I finally figured out I wasn't getting any younger and decided I have to get serious again about my health. Basically, I put on about 60 pounds since '97 that I'm looking to get rid of. I've been back at the health club for about a week. The cardio training I can deal with. It's the weight work I need brushing up on. First, not surprisingly, I overdid things last night and now I'm paying for it. My pecs are really sore and I've been walking around work like I'm in a straightjacket, trying not to move my arms. What's the best way to treat a muscle strain--with cold or heat? I know you aren't ever supposed to apply heat if you suspect there's some bleeding, but in this case I doubt it's an issue. Also, I must have no muscle tone. After I first hit the weights Sunday, I didn't feel any pain. But my muscles felt totally drained, like I had a couple of dead weights hanging from each shouder. Is this sensation normal until I start building up muscle strength? I'm not really into supplements, but is there any food or drink that can give the muscles a quick energy burst or help them heal more quickly?
