. 10-Minute Cardio Don't have time to get your cardio in? Well, you may need to think again. I had to. One of the men profiled in "Fit Over 40" is 80-year- old fitness guru Dr. Len Schwartz. Len is the creator of "Heavy Hands", and has been training for years using 10-minute sessions several times a day rather than one long session. He's also under 10% body fat! Personally, I figured he was just naturally lean. I mean, you should see this guy. But, he's not -- and this idea has more merit than one person's plan may indicate.

Research at several major universities, all done in the past two years, are showing the same results:  10 minutes of cardio 2-3 times per day is "equally or more effective" at decreasing body fat and triglyceride levels as one long bout of 30 minutes. That means less fat and lowered risk of disease, all in just 10 minutes a few times a day. Sounds like a bargain, especially when you consider the option may be pre-mature death and obesity. This doesn't have to be 10 minutes of all-out, gut-busting effort, but it needs to be more than just a casual stroll. One of my biggest challenges with cardio, and see if you don't agree, is the boredom factor. I can train with weights until cows start to bark, but cardio tends to bore me silly. Well, the beauty of this new data is assurance. Even I can be boredom-free for a whopping ten minutes, especially when I know I'm burning body fat, helping my heart, and assisting my body in recovery from weight training all at the same time. There you go -- you have all the time you need. Yours in health, Jon Benson Creator/Co-Author "Fit Over 40"
