The SPRINT 8 program found on Vision Fitness® treadmills was developed with Phil Campbell, MS, MA, and author of Ready, Set, Go! Synergy Fitness. Mr. Campbell is an expert in the field of anaerobic exercise, which has been cited by numerous medical publications as the cure for somatopause or the “middle-age spread.” The “middle-age spread” is the energy decline, weight-gain, loss of muscle, and wrinkled skin we experience after age 30. Vision Fitness is the first fitness company to integrate anaerobic exercise programming (SPRINT 8) into our equipment that specifically promotes the natural release of human growth hormone. This hormone—the most powerful body-fat-cutting, muscle-toning, anti-aging substance known in science—is produced by the body during the SPRINT 8 workout. T he SPRINT 8 anaerobic program helps people of all ages and fitness levels reach their goals. Once you press the SPRINT 8 button and select your level (from 1 for beginners to 16 for elite athletes), you are launched into an effective, heart-pumping, 20-minute workout that produces instant results. The treadmill will automatically adjust the speed and elevation based on the level you selected and will notify you when they are about to change. You can adjust the intensity at any time during your workout. Ask your authorized Vision Fitness® retailer for more information on the medical research-based SPRINT 8 program found exclusively on Vision Fitness® equipment.
