When you hear that lifting weights helps people look younger you probably think along the lines of exercise and toning equals weight loss and a younger physique. And while that's obviously true, it's not the whole story. Strength training in particular can actually help you look younger from the inside out by encouraging your body to produce more of a particular growth hormone that is linked with age-related muscle loss and bone density changes.

As we age our bodies slowly decrease the amount of growth hormone produced, but strength training is a natural and healthy way to counteract this process. Just one more reason not to skip the gym!
