"Since my joining, my physical, mental and emotional health have improved. My recovery from having my third son was so much smoother than after my first two, which I attribute largely to Fit Body. My strength came back more quickly and for the first time, I had zero signs of postpartum depression. Wherever you are at in your fitness journey, I highly recommend giving MV Fit Body Boot Camp a try!"

“Berkley Fit Body is AWESOME. When the boot camp style gym I previously went to closed, I was devastated and never thought another gym would compare. Not only does Berkley Fit Body meet the expectations set by my previous gym, it significantly exceeds them and provides me things I never knew I needed!”

"At my heaviest point and most unhealthiest, I decided to give this gym a try after a recommendation. I am SO glad I did! We are all a family and support each other 110%. No judging. I've learned how to eat healthy, have gotten incredibly strong, lost over 55 pounds, and am happy to stay in the best shape of my adult life.”

“I was really hesitant when I signed up 2 months ago. I did not think I would enjoy the workouts and honestly had no clue if it would make a difference in my life. I was COMPLETELY wrong. Thanks to Fit Body, my body is slowly changing for the better and my confidence levels are growing. I honestly couldn't think of a better place/environment to help better your body and mind!”

“I am approaching my 2 years there at Fern Creek Fit Body. I have a BAD knee and thought I would try the place. I LOVE THIS PLACE. This place is for all people at all different levels of what each individual can do in a work out. I have lost some weight and I have built my confidence. Most of all I have a new extended family. Not only the staff but other members are always welcoming, helpful and encouraging.”

“When I first started in November of last year, I had high blood pressure, high cholesterol, and I was pre-diabetic. I constantly felt tired, suffered from headaches almost everyday, and absolutely hated doing anything active because my back and my joints always hurt. Now, at almost 40, my energy level is better than it was in my 20s, my blood pressure is in the normal range and I’m no longer pre-diabetic. I recommend Fit Body to anyone and everyone who’s looking to make a positive change in their lives!!”

With 20-30 participants per session and at least two fitness coaches on hand, you get the benefits of personal attention without the hefty price tag.
