1:02 Underwater 25y

After a quick lesson from Coach Mark Hill on how to maximize my lung capacity.  I nearly doubled my underwater breath holding ability.  I consider myself relatively pathetic on the breath holding front.  Other swimmers (and probably many non-swimmers) have no problem holding their breath for 1:00 or more.  I found myself maxed out at :35 seconds a few weeks ago.  Today we were told to swim a 25y underwater as slow as possible.  I first hit :40 seconds, then :57, then 1:02 and 1:00.  I was impressed with my increases but I'm certain I rank among the lowest regarding lung capacity.
