Do you know how muscles are made? Yes, they're made by lifting weights, but do you know the process that your body goes through to make them? Do you care? If you do, here's an explanation from the experts at eDiets:

When you strength train with enough of a load to challenge yourself, your muscles experience micro-trauma and have to rebuild themselves, with help from the human growth hormone, which in turn uses fat to aid in producing muscle. It's not easy to build a pound of muscle, but once you do, you can expect to burn an extra 30 to 50 calories a day.

So while doing cardio at the gym will burn fat, don't forget to work those weights too!
