You can make a good workout in 15 minutes if you have time constraints. Lifting dumbbells is not the pinnacle of exercise. Do sprint-related things or other high intensity training. It's been proven to have as much of an effect as distance running, with the added benefit of increased metabolic rate and more muscle gain. |
