Get Fit in 6 Minutes a week?

I had to read this NY Times article twice to fully digest it. Scientists studied 2 groups of college students riding stationary bikes.

The first group exercised furiously for 20 to 30 seconds then rested for 4 minutes. They repeated this cycle 6 times.

The other group rode at a sustainable pace for 90 – 120 minutes.

Both groups exercised 3 times a week.

After 2 weeks both groups showed an identical increase in endurance.
