We have been told for decades now that the way to get healthy, lose weight, and be good to our hearts is to do 3-4 hours of cardio workouts each week. If you are anything like many other people, the thought of this is…um…well, boring! “It takes too long” is often a major complaint as well.
What if I was to tell you that this 3-4 hours of cardio workouts does not actually strengthen your heart? When you work out at a moderate intensity for long periods of time you actually condition your body to expect moderate activity all the time.
Let me elaborate a little bit. Long workouts mean that the best energy source your body can have is fat. Yes, you burn fat if you work out long enough but you also signal your body that fat is your preferred energy source and the body will be very kind and provide a ready supply of fat for you to use. This means that it is very hard to lose fat pounds while doing cardio workouts! It also means fat pounds increase when you stop cardio workouts.
Long workouts at moderate levels also condition the body for endurance and while this sounds like a good thing, what the human body really needs is strength. During normal life we have times of exertion that require more strength in the heart and lungs than endurance. Examples: picking up a heavy box, moving groceries, lifting your children/grandchildren, cutting wood, shoveling snow, some gardening, and even love making.
To build heart strength, as well as other muscles and lungs, the body must be challenged. I have read articles and books from two medical doctors that have been recommending this type of exercise for years and have seen wonderful results. Dr. Al Sears calls his method PACE (Progressively Accelerating Cardiopulmonary Exertion) and Dr. Mercola calls his method Peak 8.
Both techniques have a tendency to copy nature. Instead of long workouts at a moderate intensity, the workouts are short intense bursts of activity followed by recovery. Have you ever watched a cat chase a squirrel? They first watch for the ideal moment, and then spring into action trying to catch the squirrel. Within about 30 seconds or less it is over…the cat has either caught the squirrel, or, as often in my backyard, the squirrel has again gotten away. The cat then sits and rests and then moves on. I have never seen a cat run a marathon!
Working out at an intense level for short bursts signals your body to increase muscle strength and build lung power so that you have the oxygen and energy needed for these activities in the future. It also tells your body that fat is a very poor source of fuel as it takes too long to burn for energy and will start to store more energy as glycogen in the muscles. The body will actually burn more fat after the workouts and then stores less fat later.
The other really nice thing about this workout strategy is that it requires much less time! You can use this technique with walking, jogging, biking, swimming, jumping rope, squats, tennis…the list goes on! A key to this type of workout is the intensity. An example of high intensity would be if you can only do 30 seconds at that intensity and then get out of breath. After the short burst, let your heart rate and breathing return to normal before your next burst of energy. Hours of exercise can be done with only 10 minutes of exertion.
