Oh my gosh, Larry Weisenthal, I used to debate him on Usenet probably 7 years ago when I was on the Zone! Hmm, I hope my writing ability has improved more since then than his has...

Anyway, I totally agree with ItsTheWoo that anything that applies to real athletes (whose bodies probably are different in many ways than mere mortals) can be pretty much disregarded by your average overweight person just trying to get their daily/weekly exercise in.

When I swim for exercise (not too often these days), I spend a significant number of laps with a kickboard, so that I can pull in more of those large muscle groups.
