    "Joining 9Round has made me healthier, thinner, and it has made me feel better about myself. I have lost more than 50 lbs and gone down from size 18 to size 8. I also have more muscle than ever. I wouldn't have lost the weight and become healthier without the wonderful group of trainers at 9Round."
