As with diet, the goal here should be to find an exercise plan that will seem less like an intervention and more like part of your existing lifestyle – something you can incorporate easily into your routine. You can seek greatest cardiac workout ever, one that will put you in marathoner shape. But if it requires you to remake your life it will probably be a flop you’ll never maintain it over the long haul, and the discouragement alone will leave you worse off than before you started.
Besides, you don’t really need a Marine Corps, level exercise programmer to have a healthy heart. What you need is a daily dose of activity that will achieve the desired effect as efficiently as possible. Anything beyond that is optional. Too many people approach this as an all  or nothing proposition they start out with a high intensity programmer, keep it up for a short spell, tire of it, and go back to doing nothing at all. Better to find a 30-minute workout you’ll do daily. You won’t burn a lot of calories each session, but the cumulative effect will be beneficial in every way. At the very least you’ll offset the pound or two that most middle – aged people put on per year without even noticing? Clearly, people who exercise often and with gusto are better off than those who don’t. It’s not just a matter of cardiac health, either, moving your body and pushing its limits puts you in a healthy frame of mind, I believe, in addition to the many other benefits.
