re: Do you even lift, bro? Fitness or Narcissism?

In my opinion, the best view is to optimize your health. You can find plenty of information that supports lifting, in conjunction with other activities as the best way to maintain a high level of health/fitness.

Obviously, there is a bit of narcissism attached to improvements in your appearance. IF, however, your appearance is the only measure of success, you will likely fail in maintaining results.
