Q: Is that one-minute workout too good to be true?
Oz Says: It's pretty great, if you understand how it actually works. One study found that supershort bouts of intense exercise had the same benefits as workouts that were done at a constant pace for 50 minutes, but some reports got a little blown out of proportion. So let's clear up a few things:
1. The "one-minute workout" actually takes 12.
People who did the speedy routine exercised for 12 minutes every session, says Martin Gibala, PhD, study coauthor and chair of the Department of Kinesiology at McMaster University in Hamilton, Ontario. After a two-minute warm-up, they did a 20-second all-out sprint, then recovered for two minutes. They worked that 20-second/two-minute pattern twice more before cooling down for three minutes. So 60 seconds accounts for only the very hardest work.
2. It can do many things, but not everything.
Both short and long workouts improved fitness, plus people's ability to process blood sugar and build energy factories in their cells. But you'll still need to strength train and work on your balance and flexibility separately.
3. It's fine to stick to your longer, lower-intensity workouts.
Intervals are a faster way to get results, but if you don't like doing them, they're not a must.
