At ABL Fitness, our mission is to provide adaptive fitness and medical fitness services in Massachusetts that support individuals of all ages with and without disabilities in achieving lifelong health, independence, and confidence through movement.

We are dedicated to creating a safe, inclusive environment where neurodiverse athletes and individuals of all abilities feel a true sense of belonging, while building trust through intentional coaching, meaningful connections, and individualized support.

Through evidence-based fitness, specialized expertise in exercise science and sensory informed strategies, and personalized adaptive strategies, we empower every individual to reach their fullest potential physically, socially, and as leaders in their communities.

The Financial Challenge

Adaptive fitness typically costs 2-4 times more than regular gym memberships due to additional staffing and supports, creating an unfair “Disability Tax.” Limited funding options (like DDS, MassHealth, and SSA) and strict income rules make it tough for individuals to afford these essential programs.

At ABL Fitness, we’re committed to making fitness accessible, affordable, and available. We have the training to tackle the fitness obstacles but need your help to tackle the financial obstacles. Your partnership allows us to offer our services to individuals with disabilities for the same price as those without.

Why ABL Fitness?

Breaking Barriers, Building Opportunities!

At ABL Fitness, we believe fitness should be for everyone—no exceptions! But for individuals with disabilities, finding the right environment can be tough. Here’s where we step in:

Comprehensive Support

Many individuals with disabilities need supervision, structure, and support to fully enjoy fitness — and we provide all that and more!

Inclusive Environment

Typical gyms can feel overwhelming or unwelcoming. At ABL Fitness, every athlete is seen, supported, and celebrated.

Specialized Coaching

There’s a shortage of trained professionals ready to coach adaptive athletes, which is why our coaches specialize in inclusive, individualized training.

Individualized Programs

One-size-fits-all classes don’t work. Our programs are tailored to every ability level — challenging when it should be, supportive when it needs to be.

Peer Mentorship

Peer mentorship is a cornerstone of what we do, helping athletes build social connections and lifelong friendships.

Frequently Asked Questions

We know finding the right fitness environment matters. Here are answers to common questions from families, athletes, and healthcare providers.

What makes ABL Fitness different from a traditional gym?

ABL Fitness is a nonprofit medical fitness clinic that provides individualized fitness programming for children, teens, and adults of all abilities. Our coaches have backgrounds in exercise science, adaptive fitness, and neurodiversity support, allowing us to create structured programs focused on strength, confidence, regulation, and meaningful connection.

What is adaptive fitness?

Adaptive fitness is an individualized approach to exercise that adjusts coaching, communication, environment, and programming to meet each person’s unique needs and abilities. At ABL Fitness, we focus on building strength, confidence, regulation, functional movement, and meaningful connection in a supportive environment where athletes of all abilities can succeed.

Do you work with autism and ADHD?

Yes. ABL Fitness specializes in working with individuals with autism, ADHD, and other neurodiverse profiles. Our coaches use structured routines, individualized communication strategies, visual supports, and adaptive coaching methods to help athletes feel successful, safe, and connected through fitness.

What ages do you serve?

ABL Fitness provides programs for children, teens, and adults across the lifespan. Our programs currently serve athletes ages 5 through older adulthood.

Do parents stay during class?

It depends on the athlete and the program. Some athletes benefit from caregiver support during the transition into a new class, while others participate independently. Our goal is to help each athlete feel safe, successful, and appropriately supported while building confidence and independence over time.

Can DDS funds be used?

In some cases, yes. Families have used DDS funding, self-directed supports, and other community-based funding sources for fitness and wellness programming. We are happy to discuss documentation and determine whether our programs may qualify within your individual plan or funding structure.

Do you offer Special Olympics training?

Yes. ABL Fitness offers Special Olympics training opportunities, including powerlifting preparation and strength programming. Athletes work on strength, technique, confidence, and competition readiness in a supportive team environment.

Where are you located?

ABL Fitness is located in Wellesley, at 12a Mica Lane, and serves individuals and families throughout the Greater Boston and MetroWest areas.

Do you offer 1-on-1 sessions?

Yes. We offer individualized 1-on-1 training sessions for athletes who benefit from personalized instruction, medical fitness support, skill development, or a quieter environment before transitioning into group programming. Sessions are tailored to each athlete’s goals, needs, and learning style.

What is the difference between Adaptive and Limitless classes?

Adaptive Classes: higher-support, specialized programming primarily designed for athletes with neurodiversity (e.g. ADHD, Autism) who benefit from individualized coaching, modifications, structure, sensory support, and smaller ratios.
Limitless / Inclusive Classes: mixed-ability community fitness where athletes with neurodiversity and other disabilities train together with peer mentors, in a more social and community-oriented environment.

Testimonials

What our community says about us

My 7yo daughter has been participating in Karen’s Ninja Fitness class for 6+ months, and I can’t tell you how incredible this class has been for her, both physically and mentally. Her fitness skills and endurance have greatly improved from week to week and she’s learned a lot about healthy habits overall. The best part, though, is that her confidence has grown immensely. She is more open to taking on challenges now, and the pride she feels with each accomplishment (big or small) is so palpable and amazing to see. Karen has been terrific with her, knowing exactly how and when to push her and always making her believe in herself and her ability to learn something new. When I asked my daughter what she would leave as a review for Karen, she said, “A million thumbs up!”

Karen is FANTASTIC! She is extremely knowledgeable about all things related to physical therapy, while also being incredibly kind, accommodating, and so upbeat. My daughter feels respected and understood, and leaves the session with a sense of accomplishment. Her body and her sense of self are growing stronger, which is all I could ask for.

Limitless Fitness is amazing! It offers quality exercises with real fitness movements that are adapted to my son's ability. The class and his partners help him to have fun, build confidence in his abilities, and work hard! My son really enjoys learning different movements, the classmates are also learning about why it's important to move and make healthy choices. I am so grateful to have these classes for my son! He loves the class, and I highly recommend them!

ABL Fitness is an amazing place. My two sons who are both on the autism spectrum attend sessions at ABL Fitness on a weekly basis. My older son (19) attends an individual session with a neurotypical peer who does an amazing job with him. His peer Jack is so engaging with him and motivates him to go above the goal set for him. My younger son (16) loves attending the Saturday Limitless Fitness Class. He enjoys exercising and playing games in an inclusive environment. His favorite thing to do is play dodgeball and doing a burpee if he gets tagged with the ball. Karen, the owner, has created a wonderful space for her athletes to work out in a fun and inclusive environment. I feel like my boys have joined a great community where they can get healthy and have fun at the same time with the amazing staff and peer models. Check them out, you will not be disappointed.

ABL has been a fantastic experience for my son who has special needs. He loves working with Karen and we have noticed amazing improvements in his balance, strength, coordination and well being over the few months he's been getting one on one therapy. Not only has he benefitted, but he has shown others how independent and active he can be! Karen has a wonderful style balancing challenging exercises and work outs with encouragement and positive reinforcement getting the most out of each client's effort and ability. ABL Fitness and Karen have succeeded where so many others have failed and the benefits are obvious!
