"Because he was able to run injury free ... he discovered the athlete within himself"

"Sports Medicine Professionals know that overweight individuals put excessive wear and tear on weight bearing joints, especially the knees. Studies have shown that every pound of body weight yields anywhere from 1.5 - 5 pounds of force on the knees.

For the contestants on The Biggest Loser, the AlterG? Anti-Gravity Treadmill? is a not only a preemptive solution to potential knee problems, it is an essential part of their weight loss program and journey to a healthy lifestyle.

Colby was 120 pounds overweight when he was cast on The Biggest Loser, Temptation Nation. He was still approximately 80 pounds overweight when he discovered the benefits of running, and it soon became his passion.The AlterG was an integral part of allowing Colby to embrace this new found zeal and run his way into the hearts of viewers.

Colby made the AlterG a mandatory part of his daily workout routine.He was soon able to walk, jog and then run distances that had in the past been unachievable due to his weight and the compounding force on his knees. He could then transfer this ability to the open road with confidence.

This single piece of equipment gave Colby the chance to do something extraordinary. Because he was able to run injury free while participating in one of television’s most grueling weight loss programs, he discovered the athlete within himself. As his mileage and confidence increased, his weight continued to drop significantly. He lost enough weight to secure a spot as a finalist. He heads home a new man, with the ability to continue making running a part of his healthy lifestyle."
