9. Bruce Springsteen
At 63 years young, Bruce Springsteen is still looking good, and part of his great physique is due to his healthy lifestyle. He also lifts weights, hits the pavement for a daily run, and mixes up his routine with cardio daily. While considered “most vegetarian,” by PETA, he follows a meatless lifestyle for the health reasons. He says that in doing so, it has contributed a lot to staying healthy and make it possible to do 3+ hour sets.
