Looks like Lochte (he's 27) will be a dominant swimmer at this year's Olympics. He buried the competition on Saturday in an individual medley race (Michael Phelps came fourth). he did well in 2008, but was still disappointed.
NBC ran an interview with him - John McEnroe did the interview - before the race, with some video of his workout regimen. There are several videos of him online - here's one that's a 2 minute gatorade commercial and is pretty neat. Gatorade Inside The Edge: Ryan Lochte
The one below a bit of an advert for the gym where he works out. His trainer is an ex-Strongman competitor. It seems like every sport now puts an emphasis on dynamic weight training and jumping drills.
