I used to be a competitive long distance runner. Day in and day out I’d run mile upon mile, training for the next big race. Some days it meant running a six or seven mile loop that included several (seemingly endless) hills. Other days, I warmed up for a few miles then hit the track for sprints. Run 400 meters. Walk 100 meters. Run another 400 meters. Walk 100...you get the idea. This interval training on the track, although not representative of any race I would run, primed my body and helped me stay in shape—and boy was it a tough workout! Runners and cyclists have utilized interval training for decades. However, exercisers at many different fitness levels can benefit from this type of workout—just adjust it to fit your specific workout needs. Since interval training can be demanding, you don’t need to do it every day. My track and cross country teams trained with intervals twice a week, and focused on other cardio (longer distances) on the remaining days. Why do an interval workout? If you’re stuck in a workout rut, intervals can be a new and interesting way to get motivated and in shape. You’ll strengthen your heart, and future workouts will feel easier. Like any workout, it will help burn fat and calories, while also building endurance. Plus, with interval training the possibilities are endless! No matter what mode of exercise you choose (treadmill, outdoor walking or running, swimming, elliptical, cycling), every workout can be different and the variety within each session keeps things fresh and fun. If you are sick of walking on the treadmill for an hour each day, adding intervals can jumpstart your body out of its low-intensity cardio rut. The premise of interval training is simple: When you vary your effort by mixing periods of high and low intensities during your workout, your fitness will improve faster and more dramatically—and your workouts will be less boring. During your session, you’ll alternate between shorter, high-intensity intervals and longer, lower-intensity recovery periods. The high-intensity intervals can be "anaerobic" (where you are working as hard as you can, and your heart rate is usually over 85% of your estimated maximum), or simply more intense, like in the 75-85% range, which is still “aerobic.” You'll know when you’ve reach an anaerobic intensity because you'll start feeling a burn in your working muscles. Adding some anaerobic intervals to your workouts will usually give you better results. But since they are more demanding, anaerobic intervals should be shorter and accompanied by longer recovery intervals. As your fitness level improves, both the length of the high-intensity intervals, and the amount of work you can handle during them, will increase. Continued › |

These movements tend to involve the entire body, and concentrate on the midsection (if they're done right). Also if they are done right they are good meditation, since focus is on relaxation and concentration. And since you are also increasing your ability to defend yourself, you get more bang for the buck, as the saying goes.
One of the best self defense techniques is running as fast as you can, over all sorts of terrain (even in your own house), mixed with walking when you are too tired to run. This is also good interval training. - 4/14/2013 12:11:49 PM
how are you doing on your interval training ? - 4/13/2013 9:14:56 AM
To answer the question "Can Intervals be done IN THE POOL"
YES! Basically interval training means that you vary the intensity of your workout, so swim at "sprint speed " for a short period of time until you heart rate in up, then at a slower pace while you recover, repeat this cycle just like the article recommends for running! - 4/13/2013 6:01:02 AM

Let’s put this in perspective: Say that you worked out at 8AM on Saturday. By way of metabolic resistance training or interval training, you’d still be burning calories from that workout while out at the TV on Sunday.
You want to burn calories while watching Sunday football? Now you can.

To the greater point of the article: slow-go cardio does very LITTLE in the way of fat loss. And unless you have some specific training goals, say, run a marathon, there is very little need to actually engage in slow-go cardio exercise.
One study showed that a research group compared 20 weeks of endurance training vs. 15 weeks of interval training. The results: While the aerobic/endurance group actually managed to burn more total calories during exercise over 20 weeks (logical they trained 5 weeks longer), the interval training group lost NINE TIMES more body fat. NINE TIMES.
More FAT LOSS in LESS time of exercise.

BTW - I am 53 with single digit body fat, can run a 3-hour marathon and 19 minute 5k, canoe 8 miles an hour, do 80+ push-ups in a minute, do 30-35 good chin-ups. I can do this BECAUSE I do HIGH intensity exercise, regularly. I also believe HIT with weights to be the BEST form of exercise there is, as long as it's done correctly.

Now at 58 I still do this type of exercise, but a lot less of it because I get tired a lot faster and don't recover as quickly. But I'm in good shape and very healthy (except for a lack of eating discipline that I'm working on). So I'd say extreme interval training served me very well.
I also do long term slow steady exercise, like working in my garden for hours at a time so that I'm worn out by the time I'm done. I think this complements interval training. Variety in exercise is always good. - 8/25/2012 10:31:36 AM
