Leg lifts may be a form of calisthenics, or exercises performed using your body weight with no other equipment. You can also do leg lifts with weights or on weight machines.
The primary difference between a leg lift with weights and a leg lift without them is the resistance created by the additional weight. Generally, a leg lift with weights burns more calories, and the more weight lifted, the more calories you'll burn.
If you do calisthenic leg lifts for 10 minutes and you weigh 150 pounds, you'll burn about 40 calories. However, if you weigh 200 pounds, you burn about 53 calories in 10 minutes of leg lifts. High-intensity weightlifting, including weighted leg lifts, burns approximately 68 and 91 calories per 10 minutes for 150-pound and 200-pound persons, respectively.
Calorie burning rates may vary slightly based on the style of leg lift. In addition, personal factors such as age, sex, muscle mass, fitness level and health status may influence how many calories you burn through an exercise.
The American Council on Exercise cautions that weightlifting and other nonaerobic exercises, such as leg lifts, help build muscle and burn some calories, but they won't burn fat as effectively as running, bicycling or swimming. If fat loss is your goal, include aerobic activity in your workout plan.
