As you get older, you want to focus on building more muscle instead of decreasing the number on the scale. At advanced ages, you cannot afford to lose muscle, organ tissue, or bone mass. Lifting weights is important as you get older because you lose a percentage of muscle every year. This affects your metabolism and ability to get rid of body fat.

With age, your bones also become weaker, especially if you're post-menopausal, which is due to lower estrogen levels—the hormones responsible for maintaining bone mass. But by creating pressure on your joints through weight-bearing exercises, you can actually help build stronger, healthier bones. So instead of focusing on what the scale says, turn your energy and attention into adopting a new strength training routine.
