Session structureIntervals often increase total burn

Two swimmers doing 30 minutes can have very different calorie totals.

How to Increase Calories Burned Swimming

Try this progression:

• Add short high-effort sets (e.g., 8 x 50m) • Reduce rest gradually • Alternate strokes to recruit more muscle • Track total active swim time

Structured sessions are usually more effective than casual unplanned laps.
