How much is too much weight for a 400m runner? I know this kid who ran 49.6 last year as a junior and weighed 171 lbs. He won his state weight class as a wrestler. This year he moved up to the 189 lb weight class and also won state.
What will 18lbs of muscle do for a 400m runner? Will he have that much more strength to power through the last 70 or so meters? Or will be just be too heavy and not able to carry his weight around the track as fast.
