Both are top notch but a question for Mixelflick.
Isn't inflammation what causes pain (which is why x-factor works so great)?
If it is then isn't not being sore the next day bad in the long run, as I always find the sorer I get the stronger I get, not in the short run maybe, but over the long term. I'm thinking that taking NSAID's would cut pain down too in the short run but they are shown to limit muscle growth (unsure where I read that though)?
