[Q.]

I know of some really good swimmers and some of them are pretty chunky. They just did an piece on TV recently about the woman who swam a mile in the waters off of antartica. She may have needed her fat to survive but some of us are trying to keep it off as much as possible.

I know there's been a number of posts about whether or not the water keeps the body temp moderated and, as a result, you don't burn as many calories. I think that you can certainly burn calories since moving through the water ought to be a LOT harder than moving through the air. There's certainly a lot more resistance.

I've also heard that you need to incorporate land-based exercise regardless. My question is, how much of each? I'm currently shooting for alternating each day resulting in three day in the water and three days doing weight (mostly body weight) training plus some additional aerobic energy system stuff.

I'm not a triathlete so I'm not going to be biking or running but I guess these folks would be mixing in that kind of training. I'm more interested in body fat management.
