1 . If you always sit indoors for too long, putting on weight may become a trouble. Tired of all that fat? If so, these sports can help you burn the most calories.

Running

“Running is one of the best calorie burners out there,” qualified personal trainer Daniel Saltos says. An average person can burn anywhere from 500 to 1000 calories in one hour of running. “Speed, pace, and tolerance are all factors that can impact this range. But running uses every muscle group in the body, allowing you to burn more calories.”

Swimming

“Swimming is a workout that produces the lowest impact on body while it still can burn 500 to 600 calories in just 30 minutes,” Saltos says. Swimming also improves heart health and increases strength—all great reasons for playing in the water.

Boxing

Not only is boxing a great way to release energy, but it also helps improve balance, builds up tolerance and strengthens the upper body and core. “Boxing helps you get a good calorie burn, too, with the average person burning up 400 to 800 calories in an hour session,” Saltos says.

Rowing

The pushing and pulling motion of rowing machines targets multiple muscle groups including the arms, core, and back, helping you to burn more calories. “An hour of rowing will burn 400 to 600 calories on average,” Saltos says.
