I'm not positive but I would have to answer Swimming.It seems to me it would use almost all muscles in the body and its a low impact workout.
Running
I would say swimming.
Ah, the treadmill, one of the best exercise equipment pieces ever, the treadmill burns calories the fastest as long as your running. Also try exercise bikes and ellipticals as they burn calories also.
All forms of exercise burn calories. Exercise that is intensive, fast-moving (like running), or high-speed will burn the most calories. Some examples are running, swimming, kayaking, jump roping, rock climbing, and hiking.
tennis burns off the most calories
There are no specific pieces of exercise equipment for reducing belly fat. You will have to consume less calories and exercise in order to lose fat. Equipment that burns the most calories will aid in this. Cardio workouts are useful for helping with this.
The key to weight lossis to eat and then exercise. You most likely want to eat a good healthy amount of food and then exercise after a half hour. A good idea would be to do cardio and crunches because it helps get the body in shape and it burns a lot of calories.
At a "hard" intensity the results were: * Treadmill - 700 Calories per hour * Stair Machine - 625 Calories per hour * Rowing - 600 Calories per hour * Skiing - 600 Calories per hour * Stationary Bike - 500 Calories per hour
