Doh! Lactic acid is fuel, not waste product.

In the annals of overturned conventional wisdom, this is a doozy.

Everybody KNOWS that lactic acid is the stuff that builds up in your muscles during exercise, slowing you down, making you burn now & ache later. Seeking faster runs, longer leaps & higher jumps, people have been tweaking their diets & training for decades in a desperate attempt to remove this offending substance.

Turns out that's not a brilliant idea: scientists have discovered that lactic acid is actually the fuel our muscles burn.
