Ranked: The Top 10 Most Time-Efficient Sports

Boxing is the best sport for losing weight in the shortest time, followed by rope jumping. With nearly half of Americans saying they don’t get enough exercise each week, this latest August 2026 study by Instant Hydration reveals the top 10 least demanding activities to burn calories fastest.

The research examined popular sports to find which activities burn the most energy per hour. The report measured each sport’s MET value, a scientifically established figure showing how many times harder an activity makes the body work compared to resting. A sport with a MET of 8.0, for example, burns eight times more energy than sitting still. These values were drawn from the Adult Compendium of Physical Activities and converted into calories per hour using a standard 70 kg reference person. The study also includes where each sport can be done and how easy it is to pick up for the first time.

 

Here’s a look at the top 10 sports that burn calories fastest:

Sport	Average calories for a 70 kg person	MET Value (Energy Cost, Multiples of Resting)	Where It Can Be Done
Boxing (in ring)	861	12.3	Ordinary public facility
Rope jumping (moderate)	826	11.8	Anywhere – no venue needed
Judo	791	11.3	Specialised or booked venue
Martial arts (moderate)	721	10.3	Specialised or booked venue
Soccer (competitive)	665	9.5	Ordinary public facility
Badminton (competitive)	630	9	Ordinary public facility
Rugby (union)	581	8.3	Specialised or booked venue
Handball (team)	560	8	Specialised or booked venue
Ice hockey	560	8	Specialised or booked venue
Tennis (singles)	560	8	Specialised or booked venue

Boxing burns more calories per hour than any other sport. At a MET of 12.3, a boxer in the ring burns 12 times more energy than someone sitting still, which adds up to 861 calories gone in 60 minutes. Beyond the calorie burn, boxing also trains the whole body at once, with the legs, core, shoulders, and arms all involved from the first bell.

 

 

Rope jumping comes in second, burning 826 calories per hour, just 35 behind boxing. It’s the most accessible activity anyone can pick up, requiring no court or partner. Plus, with a MET of 11.8, rope jumping works the body almost as hard as boxing in the ring does. And other than cutting calories, it can build calf strength, foot elasticity, and coordination. 

 

 

Judo ranks third, consuming 791 calories per hour. Every exchange during wrestling involves lifting, throwing, and controlling another person’s full body weight, and this groundwork keeps the heart rate from dropping. That sustained effort gives judo a MET of 11.3, meaning the body runs at 11 times its resting rate throughout a session. It takes time to learn the basics before training feels productive, though. 

 

 

Martial arts comes next on the list, burning more than 720 calories every hour of training. A session mixes striking and footwork, so the whole body is involved rather than just the legs or arms. As a result, a single sparring round can burn 10 times more energy than sitting at a desk. Unlike boxing or judo, the intensity is also easier to manage here, since most styles let beginners start light and build up gradually without much contact.

 

 

Soccer rounds out the top five. Amateur football players can burn 665 calories in a 60-minute match, the highest figure of any team sport. This is because soccer requires near-constant running and sprinting, which also gives it a MET of 9.5. It’s also one of the more accessible sports on this list, since public pitches are easy to find and most cities have recreational leagues open to anyone.

 

The wellness expert from Instant Hydration commented on the study:

“All these sports make you sweat a lot, and sweat isn’t just water. It carries electrolytes with it, and those are what keep muscles contracting properly and stop cramps in mid-session. Losing even 2% of body weight in fluids is also enough to reduce endurance and slow reaction time. So replacing fluids and electrolytes quickly after training (not hours later) is one of the simplest things anyone can do to perform better and recover faster.”
