During a recent fitness presentation in Palm Springs, I was asked a question that didn't have a specific study to support an absolutely clear answer.
 
The question; when someone begins the Sprint 8 cardio program on a recumbent bike and only does a few of the eight sprints initially because they are not conditioned for high-intensity cardio, will they still benefit?
 
A major new study published in the Applied Journal of Physiology now brings absolute clarity to this question.
 
Researchers show that when comparing just a few 30-second cardio sprints to traditional long, slow cardio, there is a 4 to 1 time-saving, efficiency advantage for the sprints, even if it's not the full eight sprints of the Sprint 8 cardio program.
 
In other words, a 20-minute program that includes only four of the Sprint 8 cardio sprints (which is recommended initially to newcomers for the build up to the full Sprint 8) is equal to one full hour of long slow cardio.
 
Researchers report: Given the large difference in training volume, these data demonstrate that SIT (low volume sprint training) is a time-efficient strategy to induce rapid adaptations in skeletal muscle and exercise performance,
 
Keep in mind the goal is to build up to all eight sprints of the Sprint 8 and reach the exercise-induced growth hormone benchmarks within the 20-minute cardio program. But even during the build-up phase that prepares the body for higher intensity cardio and develops fast-twitch muscle fiber, there are huge time gains over traditional long, slow cardio programs.
 
The time advantage can now be measured. And there's a huge benefit for time-crunched adults of 1 minute of Sprint 8 (and this includes the recovery period) versus 4 minutes of traditional cardio.
 
Once the build-up phase is completed and your fast-twitch fiber, and heart and lungs are conditioned for all 8 sprints, you have positioned your body to tap into the benefits of the most powerful body-fat cutting, muscle-toning substance known in science.
 
Make the Sprint 8 commitment today, and perhaps consider taking the Sprint 8 Cardio Challenge. You may win an award-winning piece of home cardio equipment made by Vision Fitness. Check with your favorite home fitness store for details.
