Because both weightlifting and cardiovascular exercise burn calories, confusion arises over which is more effective in burning calories. The intensity of workouts and the exerciser's body weight are two factors that play roles in determining rates of energy use.
Weightlifting Calories
According to Mayo Clinic.com, a 160-pound person performing a weight lifting workout uses 219 calories per hour. However, a 240-pound exerciser expends 327 calories an hour doing the same workout.
Cardiovascular Exercise
A 160-pound person who jogs for an hour uses 584 calories, while the 240-pound exerciser uses 872 calories per hour, according to MayoClinic.com. By session, cardiovascular workouts clearly burn more calories than weightlifting exercise.
Post-Exercise Burn
"While it is evident that cardiovascular exercise burns more calories than lifting weights, the amount of calories burned after weight training is higher," reports the CTER Eportfolio System website. Metabolism increases after cardiovascular exercise only lasts 30 to 60 minutes, whereas post weight training metabolism increases up to 48 hours.
