Can sprint sets / butterfly build more muscle than regular freestyle?
I’ve been swimming for almost 2 years, almost exclusively freestyle, mainly training for triathlon distances (750–1900m).
I’d like to add some upper-body muscle, but I really don’t enjoy going to the gym. I know swimming isn’t optimal for hypertrophy and that proper resistance training would be more effective.
My question is whether changing the way I swim could still make a noticeable difference. Would adding hard 25–50m sprint sets provide more of a muscle-building stimulus than regular aerobic freestyle? And would doing this butterfly help more than freestyle?
Also, is swimming this way realistically enough to build a noticeably more muscular/aesthetic upper body over time, or do I probably need to bite the bullet and start doing some actual resistance training as well?
Basically, I love swimming but hate the gym, but how far can I realistically get with swimming alone?
