Disclaimer: I went back and forth whether to post this in "Conditioning" or "Bodybuilding". I decided on "BB" because I don't want to discuss the technicalities of a swimming regimen as a conditioning tool, but rather a discussion on whether is effective or even compatible with bodybuilding either during a fat-loss period or a bulking period.
The question for me is if swimming is such an effective conditioning activity (at least that's what 'conventional wisdom' says) then why have I never read of any competitive bodybuilders use it as a tool (just because I haven't seen it doesn't make it so, but it's certainly not something that's prevalent).
The 3 big conditioning (ie. fat-fighting) tools we mostly see are: treadmill, bike, stepmill.
Why not swimming? It seems that it's low impact, obviously a calorie burner, and relatively practical in terms of time spent.
Is it TOO effective (ie. likely to burn too much muscle)? Is there something inherent about swimming that detracts from bodybuilding?
Just an observation on my part that I don't remember ever reading any major bodybuilders talking about "40 minutes in the pool". If it worked, I'd think after many decades of bodybuilders doing 'trial-and-error' that it would be common.
I'm looking at this from a bodybuilder and BB lifestyle discussion perspective, hence not posted in "Conditioning".
Thoughts (especially from any competitors)?
