A Different Approach to Intervals

Because I was even more pressed for time than usual tonight, I tried Tabata intervals for my cardio session after lifting. Tabata intervals involve about four minutes of work. Yep, four minutes.

The idea stems from studies by Dr. Izumi Tabata in Japan, who found that eight sets of 20 seconds of intense work, each followed by 10 seconds of rest, boosted aerobic capacity and metabolism. It did it by doing multi-directional work, sprinting to one cone, side sliding to the next, backpeddling to another and so forth. And yes, I was winded.

It certainly was shorter than my usual 45 seconds to one minute intervals with a minute of rest. Give it a try.
