How come after workin out/lifting, those muscles do not begin to hurt the second day? The day before yesterday, i went lifting, and yesterday, i thought i was going to be scot-free without any pain, because my muscles ached only a tiny bit. But today, when i woke up. I tried to get up and *pow*, i almost fell off the bed. I was completely caught offguard by the pain in my arms and chest. It's a little better now, I did some arm stretches and things of that sort, but wow, I really didn't know it would be that bad. I guess i'll have to do some pushups or something tonight to get all the sores out.
