How Long Should I Work Out With an Elliptical Trainer to Lose Weight?

By working out on an elliptical trainer for one hour, a person weighing 180 pounds burns 514 calories, according to Calories Burned HQ. To lose one pound, a person needs to burn 3,500 calories, says WebMD. Therefore, it would take about 7 hours of elliptical training to lose one pound.

It must be noted that for this assumption to be true, individuals must burn 3,500 calories more than their calorie intake from food. Also, the exact amount of calories burned varies with a person's weight and workout intensity level. WebMD suggests cutting calorie intake together with exercise to achieve the best result in weight loss.
