Anyone for Seconds?

I tried the seven minute workout, but I couldn’t commit that kind of time. So I switched to six minute abs. But it hardly seemed worth 360 seconds when I’m already known for my signature one-pack. Then I came across something called the 1-minute workout. But I found myself saying, “I’ll get to it in a minute.” Well, I think I may have finally found the program that I can squeeze into my schedule. It’s interval training and the intervals are a reasonable length. Gretchen Reynolds in the NYT (gift article for ND readers): Exercise Vigorously for 4 Seconds. Repeat. Your Muscles May Thank You. (Oh, wait. I didn’t see the “repeat” part the first time I saw this headline. This may not work for me after all…)
