You have more wisdom than you did when you were a young man from all your years of experience—or at least, one hopes, you should—but in some settings, like the gym, you'll need to adjust your behavior even more. You might not realize it, but your body changes when you age. That's why men over 40 should take a slightly different approach to fitness than their younger peers.
You can probably still hang with younger guys—but that doesn’t mean you always should. You’ll be even stronger if you shift your workout plan to an emphasis on careful, calculated programming.

Most will use the classic Monday-Wednesday-Friday or Tuesday-Thursday-Saturday schedule. Remember to include at least one full day of rest between workouts. You’ll do each exercise as straight sets, completing all the sets of one exercise before moving onto the next.
