Hey Julie, I don't know if you've read or not, but earlier this year some new info was released that lactic acid is not a "toxin" as originally thought. This is based on the clinical work of George A. Brooks (who I think
is UCLA or Berkeley, but I know
is at least in California somewhere).
His stuff is published in the Journal of Applied Physiology, but I can't seem to pull it up right now.
But I did the get NY Times article that went with it, of all the silly things
: Lactic Acid is not muscles' foe, it's fuel
