Sprint 8 is a high intensity program that takes just 20 minutes to complete. This program includes intervals of recovery between intervals of high intensity, all-out pushes to your maximum thresholds. Sounds easy enough, right? But it is a workout unlike any other.
Sprint 8 can be done with just about any cardio workout. Begin with a 2 minute warm-up. Workout for 90 seconds at recovery level, then 30 seconds at a high intensity level and repeat the recovery and high intensity intervals 8 times each. End with a 2 minute cool-down, such as swimming, biking, running, rollerblading or any other cardio exercise for a total workout time of 20 minutes.
Sprint 8 was designed by Phil Campbell – author of Ready, Set, Go! Synergy Fitness – as a way for people to pack as much punch into their workouts as possible. During the high intensity intervals, endurance is built by working the slow, fast and super-fast muscle fibers. During and after a Sprint 8 workout, your body releases human growth hormone (HGH), which increases endurance and fights somatopause. Somatopause is the medical term for the loss of muscle, energy decline, weight gain and skin wrinkling that occurs during middle age.
For a proper Sprint 8 workout, you have to work anaerobically. So look for these anaerobic indicators during your workout:
-Out of breath, in oxygen debt
-Lactic acid burn in the muscles
-Increased body temperature
-Adrenal response
