Calorie burn varies depending on intensity and body weight, but rowing machines, ski machines, air bikes and treadmills typically offer some of the highest calorie expenditure because they engage multiple muscle groups and can support high-intensity training. Any cardio equipment can support weight loss when combined with a calorie-controlled diet.

Exercise bikes and rowing machines are generally considered low-impact forms of exercise that place less stress on the knees, hips and ankles than running. They can be suitable options for people seeking gentler cardio workouts.
