Muscle cells strengthen in response to intense exercise - whether you're 18 or 88. But the intensity is what's lacking in most people's workouts. And there are doctors who'll give you the advice, "Well, don't push it."
Jack LaLanneIf you can't afford a half hour three or four times a week taking care of the most priceless possession, your body, you've got to be sick. You're stupid.
Jack LaLanneWhat you need to do is get that tape measure out, and start measuring that gut. Then you start working out and you start eating properly till that gut gets down close to it was when you were in your 20's. Then you'll find out what your weight should be.
Jack LaLanneThe tape measure doesn't lie. Get that tape measure out and put it on your hips and your waist. Keep checking it. And keep exercising and cutting those calories down until that tape measure gets close to where you were in your prime.
