Pro cyclist Craig Lewis, the 2006 U.S. National road and criterium champ, was on hand during the demo, and he gave STACK an exclusive look as he tested PowerBar's High Intensity supplement.
Check out the following video to watch Lewis beat the burn during his grueling ride up the mountain and to get his take on using High Intensity to fight lactic acid buildup.
