  "I just wanted to share a quick note to say thank you, AJ. When Colton first came to you, he could barely jump rope. Now he's not only a pro at it, but his overall strength and athleticism has soared to a level I really didn't expect, especially in such a short period of time. He is so much stronger and more confident than I've ever seen him be. I see it in his posture, his sports and even his leadership. You've been an amazing mentor and strength trainer to Colton. I'm so thankful we came to you, and we are both happy to call you a friend."

  "I have been working out with Kylie Nelson for several months. Her strong background as both a personal trainer and a physical therapist is outstanding. She has helped me regain strength and balance. It is the personal attention and dedication that make Kylie and Dirk Nelson stand out in the gym work in Tucson."

  "1st Day and I'm hooked!!! Such a great workout! You don't have to be in shape as everyone goes at their own pace, and Kylie is great at showing modifications to help grow your confidence in each exercise. I definitely am going next weekend. I would give the class 5 stars easily. Orange Theory has nothing on B3 Fitness!"

  "I had a great workout with Kylie yesterday. I have never worked out in a gym before, and she made it easier for me as a beginner with some modifications I could do while still getting a great workout. I did better than I thought I could with her help. I encourage all women to come and give it a try. It is a great atmosphere to work out in. Thanks Kylie!"
