Why work with Kellyn


Hi, I'm Kellyn Jason! I am an experienced NASM-certified personal trainer in Hudson, Massachusetts. I hold certifications as a Precision Nutrition Coach L1 and Pregnancy and Post-Partum Corrective Exercise Specialist through Core Exercise Solutions. I earned my BS in Psychology in 2012 and am currently attending UMASS Boston for my MS in Exercise Physiology. I also work as a Graduate Teaching Assistant in the undergraduate Health Fitness Assessments course and a Research Assistant working on the Neurophysiology of Balance in Aging, primarily in older adults with type 2 diabetes and/or Alzheimer's.

With 5 years of experience in personal training, I am passionate about helping my clients achieve their goals. I take a unique approach, teaching my clients the science behind their workouts and how to successfully shift behaviors and thoughts surrounding diet and exercise.


Having gone through my own weight loss and wellness journey, I help my clients approach their goals through creating a healthy relationship with nutrition and exercise.


Client Testimonials


I'm a paragraph. Click here to add your own text and edit me. Let your users get to know you.

Kellyn is my “life saver”! Two years ago, I broke my ankle at the age of 66, had surgery, and thought I would never get back to an active life. Then I met Kellyn. She worked beyond what I would have expected from a trainer. Following two months in physical therapy Kellyn became my personal trainer. She helped me rebuild my strength, balance and confidence and gave me the encouragement that I needed to heal.
Two years later, I am still working out with Kellyn. She supports me both physically and emotionally. Her supportive nature comes through time and again. She has helped me to maintain a strong and healthy body. I have worked out for many years, but as I get older and start to feel my age, Kellyn’s gentle push has kept me challenging myself to do more.
Kellyn has an extensive knowledge base. I am still a work in progress, but with her help I am making continual strides in my strength, endurance, mindfulness, and nutrition. I have great trust in her and have no reservations about referring her to others.
