Success Stories

I love coming to class, each class is different, so the interest I have, and my muscles have, keeps me coming back to see what is next.  The personal attention and the smaller size classes are wonderful, the instructor lets me know if I am doing the exercises correctly.  My most noticeable benefit, other than feeling so much better, was skiing this past winter, I could do a complete run without stopping, something I hadn't been able to do in a long time.  A positive attitude by both the instructor and the class makes this something I don't want to miss. – Strength Class Client
I like the classes at Fitness by Design because they are rigorous and demanding, yet carefully planned and monitored to combine strength building and some aerobic components. The instructors are attentive and well organized, so I am confident that I am doing the exercises in the most effective and safe way. The classes are varied enough to remain interesting, but there is enough consistency to create a sense of real progress over time. I am not always happy while actually doing the class, but I am always glad to be there and sorry when I have to miss! I know I've gained a lot of strength and flexibility - and I've had a good time as well! – Class Client
Fitness by Design has been exactly what I needed. I am so thrilled that I found you all. My trainer has been amazing, I adore her and we have so much in common... plus she's subtly kicking my butt. And what an amazing soul Mary St. Onge is! Joining your establishment has been one of the best things I've done for myself in a really long time. Completely worth the commitment, time and money. – FBD Client
I have felt very comfortable and welcomed at your studio. Because I am "dripping wet" at the completion of each class, I know I am certainly benefitting from the classes. I appreciate the cleanliness of your studio, availability of water, a prompt starting time and your professionalism. I like that you "mix up" the routines and find them all challenging......extremely! Am I dying to come to Do I feel empowered, happier, and full of energy at the end of each class.......yes. Thank you, Barb, for wanting feedback. That speaks volumes about you and your business! – Strength Class Client
I started attending Barb Mendoza's strength class once per week just 4 months ago. I also decided to train for another marathon near that time. As a woman in my 50's, I found the strength class to significantly develop my core and overall strength and I believe this really helped me throughout the marathon and, in particular, in the last 6 miles. Barb is very good about watching individual technique within the group class and offers specific feedback to gain the most benefit. I really appreciate that! I completed the marathon taking 5 minutes off of my previous marathon time and qualifying to run the Boston Marathon! – Strength Class Client
I simply can't imagine facing the challenges in my life today without the weekly care and feeding of my physical and spiritual yoga connection with Mary St Onge. I had dabbled in yoga via DVD's, but didn't know how important the in-person instruction can be. Mary takes us all where we are, knowing every day is different, and helps us learn to acknowledge, address and diffuse the physical and mental distractions that impair our clear sense of purpose. Although that may seem a little deep, every once in a while, I just have a practice that lets me tune out the world and breathe. I am so grateful for Mary's loving leadership and her direction that inspires me to challenge myself as we practice together. Still striving for flexibility. – Margaret Buckton
If I can point out one obvious gift from God, it's having Mary St. Onge as my yoga instructor. She's a perfect fit, like a tailor made suit. She does not merely go through the motions of yoga. She plants seeds of wisdom, she explains the physical/emotional benefits of the yoga poses and is always mixing it up so you are constantly learning. I love how we actually breathe through poses slowly as opposed to sweeping through them like a hectic day. Mary is passionate about what she teaches and with that kind of energy, you get so much more from your practice. She's awesome! – Yoga Client
One of the best decisions of my life was to start personal training at Fitness By Design. I feel so much healthier, more energetic and have a more positive outlook on life. What could be more important? If you are looking for a personal trainer, you have found the very best with Barb Mendoza. She deeply cares for every client and customizes a program that delivers terrific results. – Personal Training Client
I started practicing yoga at a very vulnerable time in my life and in Mary's classes I have learned how to heal myself from within and that it's ok to take care of me first.Through the practice of yoga under Mary's guidance, I have gained more confidence in myself to handle whatever life sends my way.  I feel such inner peace every time I leave one of her classes that I can't wait for the next one. Mary is very passionate about yoga and brings that passion into every class she teaches. I highly recommend Mary to anyone who is looking for peace and serenity in their life. – Carol
Last year, I decided to take more initiative with my health. I have been working out with Barb once a week and have recently added 2 fitness classes. I've been very adamant about taking this slow and steady- I want to change how fitness occurs as a long-term commitment. I can say that the variety of activities I participate in through FBD and the exercise I do on my own have really made a difference in my daily life. I'm stronger, more fit and have even noticed that my clothing fits better. Fitness By Design has been an all-around great addition to my life. – Personal Training Client
I am really enjoying my yoga classes with Mary. I've never done yoga and I couldn't have asked for a better instructor for my first experience. Mary is fantastic - she has a very calming effect on my mind and body - can't wait for Monday evenings! – Yoga Client
As a mother of 3 young boys, it is difficult to find time to work out. I know that when I work with Barb, I will get maximum results in the minimum time. Barb has learned a lot about me and knows what to focus on so I get the most out of my workout. She is incredibly motivational and I appreciate her dedication to, not only my health, but my family's health as well. – Personal Training Client
My lungs always feel so expansive the next day, my brain is calmer, and I've lost 9 pounds! There's just something about mindfulness, energy, and quiet that is so wonderful. AND I would like to say: You, Mary, are the BEST! I've been to other yoga classes, and they just don't have the same "spiritual" tone. But it's not preachy... just simple and nice. Also, I don't ever feel that I am in danger of injuring anything. You always focus on just doing what you can without hurting anything which is perfect for me!! – Yoga Client
I have been going to strength training classes for over a couple of years now. I enjoy exercising with a nice group of people and have found the class very helpful at both improving my running and preventing injuries. Best of all....I can now see my triceps – Strength Class Client
You go above and beyond to give everyone individual attention and your dedication to making your studio great is obvious. I have worked out at many places in the last 30 years and hands down yours is the best I've been to. The classes are never the same and always challenging. I love going!!  – Class Client
My journey to a healthier life has been a slow one, and Barb has supported me all the way, pushing me when I needed it, helping me noticeably increase my balance, agility, functional strength, and confidence. This year I decided to focus on weight loss. Barb held me accountable to that, celebrated small successes with me, and helped me keep the inevitable setbacks in perspective. I've lost 20 pounds, and we're still going! – Personal Training Client
I have attended both the strength training and Yoga classes and feel challenged in both!  The routines provided by the instructors are varied and we are engaged at all times...I must also say I enjoy socializing with neighbors and friends when I am there and would highly recommend! – Class Client
Just wanted to let you know how much I've been enjoying the mixed-use yoga classes with Mary! It's a highlight of my week and I THINK I may be progressing a bit in my practice -- it's not as foreign to me now, and I've even ventured closer to the mirror and the front of the room. :)   – Yoga Client
We're both really happy with how things are going. The instructor makes it fun and pushes us, but is also attentive about any pain spots and making sure we don't aggravate anything.   – Semi-Private Training Clients
I joined FBD in late June and I have lost around 8 inches with my trainer, Janice. I find the experience very rewarding and believe I have increased my stamina and strength. I will continue on this path and see where it takes me. I can be a fairly impatient person as far as results go , but know Rome wasn't built in a it's full steam ahead! – Private Training Client
Instructors have been great. They know what they are doing. They help adjust me, and I appreciate that. Like the small/intimate setting and that there is a "sense of community." I like that I just have to bring myself, no equipment, and I am very impressed with all the equipment. People are friendly. I love the variety of options/classes, yoga, pilates, strength etc. Facilities are clean and smell good. – Class Client
Mary does such a good job of making sure I, and everyone, is comfortable. So glad I took the leap and signed up! – Yoga Client
My training sessions have been most important for my health and well-being. My trainer is excellent. She is knowledgeable, organized, safety concious, adaptable, patient, but knows how to push one towards improvement and progress. The studio is private, well equipped, and close to home, a plus for me. The staff has always been kind and fun. The experience has been well worth the money! – Private Training Client
Starting a weekly Pilates class with Jill has been a great (and much needed!) way to get back into a regular workout routine after having a baby last winter. I so appreciate Jill’s style which challenges me and is personalized to meet my fitness needs right now.  – Pilates Client
I absolutely loved the class. Mary was so welcoming and made me feel really comfortable and definitely nurtured. It’s not always easy to show up to a new studio where you don’t know anyone and Mary helped me feel at home.  I’m new to the area so I’m thrilled to find your studio. I will definitely be buying a package and trying as many classes as I can.  Thank you for being an entrepreneur who is helping to nurture us all.  – Yoga Client
I have been taking Pilates for the past three years. This past weekend I saw the power of putting it into practice. I moved over 70 bags of mulch in two afternoons. My body worked with me, I lifted appropriately, my core assisted (instead of my back), and would you believe that I was not sore the following mornings?! I cannot recommend the Pilates instructors at FBD enough! – Pilates Client
Thank you for such a warm welcome. I love your studio. It has a great vibe – it is so nurturing. Mary’s class was exactly what I needed. I realized after I started my teacher training that I needed to find a new teacher for my own practice and I think Mary is the right one for me. Thanks for the welcome gifts also! – Yoga Client
I want to compliment you on your approach. You contacted me by phone the day after I sent the email, even though you were out of state on personal time. I’ve heard from both you and my instructor personally multiple times, met with her yesterday, have another appointment booked for Tuesday AND have received several (much appreciated) automated appointment reminders that I’d expect from much larger operations. My session was great and I learned so much!  All of that service within 5 days of my initial contact. Superb job!  Well done, you! – Pilates Client
A beautiful message; a testimony of your determination and love for fitness. I am really enjoying my weekly visit to your DSM studio. It is a beautiful studio which I enjoy and appreciate.  Through the years I’ve done Pilates and many other types of classes. I feel blessed to have found Jill; her class is always challenging but she always provides options. She takes the time to continually innovate while giving us the opportunity to improve. I wish you and your staff many more successful years and hopefully “surgery free." Needless to say your studio is the best I’ve visited. Thanks again!   – Pilates Client
I enjoy working out with Diane and Susanne because they are so encouraging and supportive, plus they have a great sense of humor. They make my workouts fun. I can tell that my cardio fitness has improved significantly. Without it, I don't think I could have made the mad dash (with two bags) from Gate C23 to C5 in time to make our connecting flight in the Minneapolis airport. I also have been able to move from 5- to 7-pound weights for a variety of upper body exercises -- something I have not been able to do in years. I also have benefited greatly from having my trainers help me with my myriad PT exercises. – Lisa
3/4 of a century, not bad. Thanks for keeping me in good condition! – Class Client
Dear FBD, It’s the season for giving thanks, and I’m writing you all to let you know how happy I am that you are in my life.  I started coming to Fitness by Design shortly after I retired eight years ago, and my work with you has made a huge difference in my fitness level and overall wellness.  I am so thankful for your excellent instruction and consistent encouragement - and you make exercise fun as well!   Thank you, thank you, thank you - I appreciate you so very much! – Mary
Last night I was recruiting a friend to join your studio. I bragged about your customer care and kindness. – Claudia
