How Many Calories Does Tennis Burn?

Tennis calories depend on singles vs doubles, rally length, and how much you retrieve balls versus chat at the net. Singles grinders earn more than social hitters.

Using a working MET of about 7.3 (singles recreational; doubles usually lower), a 70 kg person lands near 256 calories in 30 minutes — roughly 511 per hour. Scale up or down with bodyweight; long rests and easy intervals pull the real total lower.

Fat loss still follows weekly energy balance. Treat class boards and wearables as a range, not a free pass for unlogged meals.

Calorie estimates by bodyweight and duration

Estimated calories for Tennis (MET ≈ 7.3) — approximate, Compendium-style intensity:

55 kg: 15 min: ~100 · 30 min: ~201 · 45 min: ~301 · 60 min: ~402

70 kg: 15 min: ~128 · 30 min: ~256 · 45 min: ~383 · 60 min: ~511

85 kg: 15 min: ~155 · 30 min: ~310 · 45 min: ~465 · 60 min: ~621

These assume continuous effort at the stated intensity. Instruction breaks, water stops, and scrolling between rounds do not count as work.

What actually drives the burn

MET ≈ 7.3 for active singles. Doubles often lands lower. Lessons with lots of standing instruction drop averages.

Heavier bodies expend more energy doing the same pattern. Intensity and continuous minutes beat the nickname on the timetable.

Wearables and studio boards

Wrist estimates struggle with load, rest, and non-step movement. Studio boards and machine screens are convenient and often optimistic.

In a cut, plan food as if the printed burn were 20–40% lower unless your scale trend says otherwise.

Training value vs calorie theater

Tennis builds agility and competitive fun. Add strength for shoulders and legs if you play often.

If physique change matters, keep protein around 1.6–2.2 g/kg and protect sleep. A calorie badge does not replace progressive work or an honest diary.

Where IGNITE AI fits

Clubhouse food is where matches go to die. IGNITE AI is the only flow that feels as fast as a short ball: snap the plate between sets or after, fix the estimate, keep the match logged — so your handicap is not your food diary.

Bottom line

Expect roughly 256 kcal in 30 minutes at 70 kg for tennis at MET ≈ 7.3, then adjust for your weight and how hard you actually moved.

Win the point. Then win the week. IGNITE AI — photo logging that keeps up with court time and clubhouse temptation.
