I've heard lots of coaches and athletes use self massage and leg elevation to "drain the fluid" from their legs after a hard workout to speed recovery. What fluid are they talking about? Sorry if this is kinda a dumb question, it's just something that's been in the back of my mind for a while and it's driving me crazy not to know. Googled it and a few sites said this "fluid" was byproducts, but I'm at a loss to know what that means too!
Anyone know
I guess it's not *that* important to find out, but it's been bugging me.
