Did you catch Torri Huske’s American record-breaking 55.66 win in the 100-meter butterfly at the US Olympic Swimming Trials? One aspect of her race, in particular, caught our attention; her breathing pattern. Torri swims the first 50 meters using a one up, one down breathing pattern. This breathing pattern is perhaps the most common pattern we see swimmers use for the 100 butterfly, but does that mean everyone should be using it?
