How Many Calories Does Tennis Burn?

Tennis calories by weight & duration

The ~513 calories per hour figure is an estimate for a 155 lb person playing recreational tennis at a 7.3 MET, and your actual number will be higher or lower based on your body weight, how hard you're working, and how much time you spend actively moving versus waiting between points. Log your sessions in the Mariposas app to track burn over time and see how your output changes as your fitness and on-court movement improve.

Calculated as MET (7.3) × body weight (kg) × hours. How this works.

What to expect in a tennis class

Your first session on a court will likely feel more physically demanding than you expect, mostly because of the lateral shuffling and sudden direction changes rather than any single stroke. If you're joining a beginner clinic or hitting with a partner, expect a lot of repetitive drilling, feeding balls from the baseline, and working through the mechanics of a forehand before you ever play a real point. The pace is stop-and-go by nature, with brief rallies followed by walking back to position, so your cardiovascular system gets taxed in intervals rather than one continuous push. By the end of an hour, your legs and forearm are usually what remind you that you worked.

Tips for your first tennis class

• Grip pressure matters more than grip type early on. Most beginners squeeze too hard, which tightens the forearm and kills feel. Try holding the racket firmly but not white-knuckle tight, especially right before contact.
• Work on your split step before your strokes. The split step is a small hop you take as your opponent hits the ball that loads your legs and lets you push off in either direction fast. Without it, you'll always feel like you're a half-second late to every ball.
• Wear actual court shoes rather than running shoes. Tennis requires aggressive lateral cuts, and running shoes aren't built for that kind of side-to-side force. A twisted ankle on a hard court is an easy injury to avoid.
• Start with a continental grip for your serve rather than trying to spin the ball. Most beginners naturally hit a flat serve with a forehand grip, which creates a ceiling for development later. Getting comfortable with continental early saves you from relearning it later.

What affects how many calories tennis burns

The 7.3 MET rating reflects moderate-to-vigorous recreational singles play, but your actual output shifts a lot depending on how competitive the match is and how much court you cover. Long baseline rallies with consistent movement burn considerably more than a casual doubles game where you're standing at the net for half the point. Calorie burn scales with body weight, so a heavier player will burn more than the 155 lb estimate, and a lighter player will burn less, all else being equal.

Three things move your number most: body weight (a heavier body burns more for the same activity, that's why the table runs from 125 to 225 lb), duration (calories scale with time), and intensity. A tennis you push hard burns more than an easy one, because effort is what the MET value of 7.3 represents, an average for this activity. Your fitness level and how much you rest between efforts shift it too, so treat these as a solid estimate rather than an exact count.

How we calculate tennis calories

Every number here uses the standard energy-expenditure formula: calories ≈ MET × body weight (kg) × time (hours). The MET value of 7.3 for tennis comes from the published Compendium of Physical Activities, the same reference researchers and fitness trackers use. We convert your weight to kilograms and multiply through, no fudge factors. See our methodology for the full formula and sources.
