Boot Camp Testimonial
I had the lapband surgery a year ago, lost wieght in the beginning, then was at a standstill. I joined Ultimate Fitness and decided to give Boot Camp a try, well 8 weeks later I have lost weight, inches and feel stronger but the most important part is I LOVE myself!! My doctor is so impressed with the results I don’t have to see her for another 3 months and my surgeon for another year! I love Boot Camp so much I signed up for another 8 weeks! Boot Camp is hard and challenging but it has changed my life!   — Malena
