Okay, so there is nothing you can really do to turn back the clock, but there are some things that happen with age that aren’t inevitable. For example, as you get older, muscle mass tends to decrease and body fat increases (in physically inactive people this starts after the age of 30), but this is mostly due to sitting more and moving less. A full body resistance program will help prevent the loss of muscle. Remember, muscle helps increase metabolic rate, which means you burn more calories making it easier to lose weight or maintain a health weight. Furthermore, muscle is a sign of youth and is vital in making the body shapely and firm.
