Workout Summary
The Ultimate Full-Body Burn
Swimming is frequently cited by fitness experts as the ultimate exercise. Water provides 800 times more resistance than air, meaning every kick, pull, and push is essentially a form of weight training mixed with intense cardiovascular conditioning.
How We Calculate Pool Calories
Our calculator uses standard scientific MET (Metabolic Equivalent of Task) values established by sports medicine researchers.
A single MET represents the energy you use while sitting entirely still. A gentle backstroke has a MET of 4.8 (meaning you burn 4.8x more energy than sitting on the sofa). A vigorous Butterfly stroke has a MET of nearly 14. We multiply this MET value by your body weight and your time in the water to get a highly accurate caloric figure.
Which Stroke is Best for Weight Loss?
1. Freestyle (Front Crawl)
The best overall choice. It's fast, efficient, and most people can sustain a vigorous pace for 30+ minutes without their form collapsing.
2. Butterfly
The highest calorie burner per minute, but almost impossible to sustain for long periods. Best used as a HIIT sprint interval.
3. Breaststroke
Excellent for cardiovascular health and targeting the inner thighs and chest, burning a steady, moderate amount of calories.
4. Backstroke
The lowest calorie burn, but incredible for fixing posture issues caused by desk work. Great for active recovery days.
