Let me ask you something.

What if you could find exercise that:

1) challenges your cardiovascular fitness (of course!)
2) builds muscle (anabolic activity)
3) invigorates and provides stress reduction at the same time
4) can be finished in 20 minutes 2-3 times per week.

Tada, it exists! And it’s right here at your fingertips and footprints. And it’s been here all along, it just got buried under all the “long, s-l-o-w” cardio information we’ve been presented with for the last few years.

The good news is, you needn’t do long, s-l-o-w to get the best benefits from cardio exercise, quite to the contrary! If you are willing to put a little more muscle and mind into the equation, you can slice your cardio time by huge chunks and come out ahead as well.

What Exactly IS Interval Training?

Interval Training (IT) involves changing speed or resistance - and thus intensity - within the course of a cardiovascular workout. Thus, instead of a slow, long distance - or long, slow time - within your aerobic intensity aerobic training “zone”, you intersperse short, intense periods into otherwise more moderate minutes.

This approach - intermittent bouts of intensity systematically built in - works better for f*at loss and muscle building than long and slow does.

Bottom line, what I best like about IT is that it aligns beautifully with my preference for “short and to the point” fitness. Bang for your buck is essential with my busy life, and IT fits the bill.

AND (there’s more!) IT creates a huge afterburn effect, in terms of elevated metabolic advantage. I’m talking for HOURS after the exercise itself…not to mention that which comes along with the added muscle from this type of exercise. Now THAT is what I call great ROI! (return on investment!)

Simply put, the easiest way to do interval training is to start off at a good pace for about 5 minutes. A variety of modalities can be utilized: stationary bicycle, eliptical trainer, jogging/walking, for example.

Then, you pick up the intensity and go hard and as fast for a minute and then bring it back down for a minute or two - however long it takes for you to recover enough to do it again. Then you repeat the process for a total of only 15-20 minutes, including warmup and cool down. It is advisable to start with one interval a session, then progress to two, and so on.

The intervals can feel more intense than you might imagine. Jack LaLanne refers to it as imagining “you are running for your life” -that’s tough stuff! And also not for the foolhardy who may have been out of condition for a long time. Doctor’s clearance is always recommended. (I always think it’s funny that a doctor’s clearance isn’t required for laying around on the couch for years at a time! )

Another way to practice interval training is simply to keep changing your speed and intensity level every two minutes or so - go up and down - challenge yourself…
