Weightlifters have more energy

You wouldn’t think so, but a brutal squat session will actually give you more energy in the long run. Spend a few hours quickly bossing the weights room each week and you'll have 20% more energy all day long, according to researchers at the University of Georgia. Why? Weightlifting deliver oxygen and nutrients to your tissues and help your cardiovascular system work more efficiently. And when your heart and lungs work more efficiently, you have more energy to hit the gym again.
