FAQ
Best stroke for calorie burn?
Butterfly > freestyle > backstroke > breaststroke. Sustained pace matters more than stroke.
Cold water — extra calories?
Yes — slight increase from thermoregulation, ~5-10%. Open-water (cold) burns more than heated pool.
Swimming for arthritis?
Excellent — water buoyancy reduces joint impact. 30 min × 5/wk recommended.
