    "After learning how much fun the 9Round program is, I've tried to work out 3-4 times a week since then. Now, instead of big, old and tired, I feel strong, balanced, and focused. I thank 9Round for the energy, environment, and guidance for my transformation."

    "I needed a motivator and I found one when I started working out at 9Round. Now, I don't have to go into a traditional gym and walk around aimlessly looking for the next activity. 9Round provides me with a new workout every day! The CHOW also provides a little competition which motivates me."
