Client Testimonials

"I've been a regular client of Devonna's since 2013, and over the last 5 years she has helped me transform my life! On my first day of training with Devonna I weighed in at 285 lbs, I had unhealthy eating habits, and had started and failed with numerous exercise programs and diets. In short, I was a "Hot Mess", but Devonna helped me change everything. With patience and professionalism she guided me on a path of recovery and self-improvement that I previously thought was unattainable. She developed individualized plans for me that combined healthy eating with strength training and enjoyable aerobic activities. She worked with me to convert these plans into daily routines that I have come to cherish and enjoy. Along the way Devonna has been a rock solid source of support, rarely rescheduling appointments, always on time and prepared, and consistently wise in her suggestions for adjusting and changing our workouts to achieve the best results.To anyone interested in improving their fitness, health and wellness, I recommend Devonna and JUMP Fitness whole-heartedly and without reservation."

- Carmen, Haverhill MA

"I have been training with D for six months. I have had many training experiences over the years, and I can say without a doubt that D is an excellent trainer. For example, my golf game has improved with core-strength and rotation exercises that she integrates into my routine. D not only provides a variety of exercises, but she also listens and adapts when I report an injury that needs special attention. Her friendly and warm personality, as well as her passion shines through with every session."

Client Testimonials

"Two years ago, as a 58 year old guy with no history of regular exercise or weight training I started working with D She quickly and accurately figured out my capabilities and pushes me to my limit in every session. I trust her judgement completely. She’s a real pro - knows exactly what she’s doing. I am much stronger, and healthier as a result of the work I do with D As I hit 60 this year I have a great deal more confidence about my physical condition. I credit my workouts with D For that."


- Sam, Natick

"I have been working with D for over a year now and she has helped me tremendously. As a avid golfer she has helped me with my golf game by developing a workout program that is geared towards strengthening my hip flexors and core. I am so excited that I am able to hit the golf balls father than I had  before. One of things that I like most about working with D is that she is able to tailor my training program due to any injuries that I may have incurred from playing golf. She is wonderful person and trainer, I am so glad to be working with her."
