Weight Loss Exercise: 30 minutes could be better than 60
If you are trying to lose weight, fitting in a 60-minute workout each day can be challenging … sometimes maybe too much of a challenge to be able to achieve. But studies indicate that 30 minutes of exercise a day can achieve the same amount of weight loss as a 60-minute workout.
- - A study of 60 healthy, but overweight, Danish men had participants workout either 30 or 60 minutes daily wearing a heart-rate monitor and calorie counter.
- The men who worked out for 30 minutes a day lost on an average about 8 pounds over a 3 month period, compared to 6 pounds for those who exercised 60 minutes daily.
- Researchers who conducted the study felt that those who exercised for 30 minutes burned more calories than they should have relative to the training program designed for them.
- On the other hand, the men who exercised for 60 minutes lost less body weight compared to the energy they burned by running, hiking or rowing.
- Part of the explanation could be that people found 30 minutes of exercise doable and that participants still had energy to be more physically active during the day.
- - Finally, researchers suggested that it is likely the men who exercised 60 minutes a day possibly ate more to compensate for the longer workout sessions and lost less weight than anticipated.

I have known this since I started Turbulence Training in 2008. In fact, I've known it since 2007 when I did Jim Karas' cardio-free program. You may be familiar with Jim Karas, as he trained Hugh Jackman and Diane Sawyer.
So why in the world, after I got my personal training certification, did I start teaching hour long cardio dance programs? I did it because they were popular, and I wanted to succeed. The only problem was, in the year after I started teaching this way,
I gained 15 pounds!
Since January, I've put three 30 minute Turbulence Training classes on the schedule at Gordon studio. The result? I've lost eight pounds, and my students are having visible, amazing results.
It may be that people who are naturally slender can do long cardio sessions and stay that way. I've been obese. When I was a child I was chubby, I had very little strength, and I had even less endurance. I struggled for years to get the figure I wanted, and it finally happened when I cut out the cardio and started Density training with bodyweight exercises, weighted resistance, and interval training. Then, after I got the figure and my certification, I went back to my old ways.
Shame on me for not following my instincts, my conviction, and my inner wisdom. I deserved every one of those 15 pounds I regained.
No more. From now on my dance fitness classes will be 45 minutes including the warm up, cool down, and stretch. This will ensure that we're never in the "Cortisol Zone" for more than 40 minutes. I get so much pleasure from dance- it's so much fun! But the principal purpose of Gordon Studio is safety, fat loss, and body re-composition.
It's funny, I saw Star Trek yesterday, and I realized I had violated my "Prime Directive." It's time to do what works according to the research and my core beliefs.
