  • I have been working out at FT for a couple of years and it has made a dramatic difference in my health. I no longer need hip surgery and I am able to dance and hike again.

  • Friendly people who care about helping you achieve your goals. FT helped me prepare to hike the Appalachian Trail at age 65. If you have the will, FT will show you the way.

  • I started working out after having breast cancer and heading to osteoporosis. My primary goal with FT was to increase bone density. I now have normal bone density.

  • The high quality training and nutrition advice at Fitness Together has helped me reach my fitness goals. I’ve lost 20 pounds and have a BMI of 22.8!
