Listen, coming from someone who finds little to no joy in working out whatsoever... Becca really did her thing here. And I will forever be a loyal client going forward. She somehow made movement feel manageable--even enjoyable--for someone like me who's usually dragging their feet just thinking about a workout. Becca is not only incredibly knowledgeable, but she also has this rare ability to meet you exactly where you're at, without judgment or pressure. My first session felt tailored, thoughtful, and empowering. I never thought I'd be someone who actually looks forward to showing up, but here we are. If you're intimidated by Pilates or just haven't found the right person to guide you yet, Becca is the one. 10/10 recommend. read more

I checked this studio out on a whim over the weekend and I'm so glad I did! I loved the boutique atmosphere and small class sizes, plus the studio itself was adorable and super clean. I took a class with Jess Cain and fell in love! I had never tried pilates before and I really appreciated her explanations and adjustments. I liked her focus on form and finding what works for your body. Plus, she is so fun and encouraging! I left class feeling incredibly stretched out and relaxed, AND like I'd gotten a really good workout in. I'd highly recommend taking her class if you're looking for an excellent workout experience! I'll definitely be back! read more

My FAVORITE pilates in Petaluma by far! The classes are not only amazing for my physical health but also my mental health. If I could go everyday I would lol. All the instructors are so sweet and happy to help with any modifications if needed. The owner, Becca is wonderful! I love her classes. Definitely recommend! read more

If you want a Pilates class that starts right on time; has music at a moderate level rather than blasting and is not chatty the whole way through so you can settle into focusing on your body and the exercises; is efficient and ever changing to keep things interesting; and has a warm, attentive instructor who's paying attention to your form and needs, adapting as needed, you've found your place! I surveyed/tried about 5 Pilates studios in Petaluma and settled on this one. I'd recommend them to people intimidated by Pilates as well as athletes. read more

I LOVE this Pilates studio! Convenient location and Rebecca kicks your butt!! The only thing I wish is that she was available for more classes outside of her MW schedule. read more

Foundation Pilates is fabulous. The studio offers terrific hours, is clean with good instructors and use the wooden balanced body apparatus that I prefer. Semi private classes make it easy to keep Pilates in my workout repertoire. The owner, Becca is professional & personable. An added bonus is that she has great taste & great recommendations when I need completely different services oh and she loves dogs! read more

I have taken a few classes at foundation Pilates from Danelle. She is such a kind,well educated Pilates instructor. I can't wait until Sonoma county gets to stage 3 so that I can't cone back. read more

What I really like about Foundation Pilates is that the owner, Shelbey, is extremely supportive. She tailors workouts to the individual and seems to have a endless and creative supply of new routines. She trains her workers to do the same. Every time I've started to get used to the routines, they were changed - and this is a GOOD thing. I was totally out of shape when I started - weighed over 180 (at 5'1"). Now, people look at my "fat" picture and don't believe it's the same person! I feel great. I've been to 2 other Pilates places, but Foundation is the best as far as I am concerned read more

Worked my ass off. Incredible instructor who helped me work at my peak, and kept me safe and injury-free. I wish I'd found her years ago. But so happy I've got her working me out now. I'm not naturally drawn to working out. But I feel so good after these classes. I'll keep coming back for the personal attention. read more

The best Pilates studio ever! I'm a newbie but I'm hooked! I leave my classes feeling so good mentally and physically. I have worked out parts of my body I never have worked out before EVER! I can feel my body getting stronger with every session and I'm so glad I took a chance and tried it out! Definitely recommend! read more

Love this place. I will start by saying that I'm not a "group activity" kind of person. I don't like big classes. I'd also never done pilates or yoga. Foundation was recommended to me so I figured I'd give it a shot. First class was complimentary- so what did I have to lose? Class size never exceeds 5 people- and honestly - I have only seen the class full one time. Being so small- allows them to concentrate on each person. I never felt "silly" or awkward for not knowing the moves or pace. Each teacher really works with you, to your level. Price is reasonable- packages are the way to go. You can sign in for classes online (recurring or individual). It even allows you to see how many people are already signed up. I felt toned and my husband said that he could really see the difference after a month. Glad I found them. read more

Foundation Pilates is a Petaluma gem!! They offer a variety of classes that they tailor to your goals and abilities. Their knowledge of how to also personalize exercises around an injury you may have or help target muscle groups that will benefit you in your career/day to day activities is phenomenal. Liberating to find a studio where you're not stuck in a cookie cutter routine. This place is a must for any fitness junkies! Consider yourself warned, you'll be pushed outside the limits of your comfort zone and get addicted to the progress you achieve. read more

This is the first pilates studio that I have been to and I am hooked. The owner, Becca, made me feel comfortable because I was a little intimidated by the reformer equipment. After several privates, I felt comfortable enough to take group classes. I was reassured to find the classes very intimate with 5 people maximum in a class. Becca accommodates each fitness level in a single class. I've been going to Foundation Pilates for over a year now and my body is in the best shape I've ever been in. I will be moving to LA next month and began my search for a new studio and nothing compares. If your looking to build long lean muscle and to strengthen your core, look no further. I highly, highly recommend. (The first class is complimentary when enrolling online) read more

Foundations Pilates, Becca and staff do a stellar job. I love my classes and find myself laughing during the classes because I am having so much fun. I really appreciate the cleanliness of the studio, the cool vibe, music and the ease of location. If you have felt you can not do Pilates I highly recommend you take a class. The staff is skilled and gentle. I felt comfortable the whole time I learned the processes. I felt this way with three different instructors which indicates that the staff is well trained and kind. I love that there is no pretentiousness from the staff or clients. My body feels engaged during my workouts and energized afterwards. I am so grateful to find this business. Pure joy to workout in a effective and exciting way!!!! read more

I've been coming to Foundation Pilates for about a year and a half, and I can truly say it has changed my life. After spending much of my adulthood as a couch-potato, I now have a fitness routine that I LOVE! Who knew exercise could be so much fun? Because of Pilates, my blood pressure (which has been high for years) is lower, I have more flexibility and better balance then ever before, and best of all, I can see tone and definition in muscles I didn't even know I had! The owner, Shelbey, is one of the nicest people you'll ever meet, plus she is extremely knowledgable about fitness. As an intructor, she is encouraging and supportive, and she custom-tailors the routines to her clients' needs. If there were a rating higher than five stars, I would give it to Foundation Pilates. read more

Foundation Pilates is the best Pilates studio for many reasons including that the classes are small so you're practically getting a private session. The staff is AMAZING!! Shelbey and her team go above and beyond to meet your needs and make sure you're meeting your fitness goals. The studio is extremely clean and the reformers and equipment are like new. Going to the studio is a lovely escape from the day's stress. I started doing Pilates to get in shape for my wedding and I love it. I've never looked forward to a workout so much in my life. It's been almost a year since I started and I'm telling you it's the BEST! No matter your age, size or shape the workouts are customized for you. Go in for one class, and I assure you, you will be hooked!! read more

Love taking Becca's Pilates classes! She makes me feel so comfortable and never pushes my body to hard! My body feels in less pain since I've been taking the classes as well! Highly recommend!! read more

I took my first Pilates reformer class at Foundation Pilates this morning with Beth. She was great! She explained everything really well and I felt like I got a great full body workout. The studio itself is really nice as well, very clean, open and inviting. I will definitely be back! read more

Foundation Pilates is an amazing studio. Becca has created a perfect environment for the best workout around. Her instructors are very educated, nurturing and fun. Since it is a small studio, you feel like you are having a private lesson. Speaking of the studio, the equipment is state of the art, clean and lots of "toys" to play with! If you have never tried reformer pilates or you are advanced, this is a great place to get your core on!!! read more

Love this place! Great classes, teachers are proficient in there teaching of pilates, barre, tower & jump board.

I've been going to the gym for years, but this workout is the one that has helped me improve my flexibility and strength at the same time. The staff has a great attitude. Scheduling is flexible. I am really fortunate that I found this studio. read more

I have been coming to Foundation Pilates for about 6 months and I love it. I have degenerative disc and have suffered back problems for many years. Shelbey tailors the work out to accommodate my limitations but she still pushes me enough that I am feeling and seeing great results. I highly recommend Foundation Pilates. read more

I am still hooked on Pilates. The instructors here are amazing! The workouts are always creative & new. Everytime I have a concern about my body it is immediatly addresed, & they do an amazing job catering to any injuries. I recently got married & they helped me work on all my tough spots that were really important to me. I felt so confident on my wedding day & in a bikini on my honeymoon :) Thank you Shelbe read more

I thoroughly enjoyed my semi-private session with Becca. Lovely, clean, well maintained studio and very knowledgeable instruction. Next time I visit Petaluma, I will certainly return! read more

Shelbey, Becca, and Sara all have their own style, and they are all TERRIFIC! They are all supportive and able to meet each person where they are 'at'. I have been attending regularly for three months. My lower back had been bothering me, and I wanted to get stronger. Pilates is a great addition to the Ivengar yoga I love. I look forward to every class. Additional benefits - ridding the stress in my body and better sleep! And my lower back is no longer bothering me! read more

I have been teaching in this town for over 30 years. I started Pilates reformer instruction 6 years ago. Foundation is the best studio in town!

Makes for such a happy place to work, The clients are awesome as well.... read more

Perfection. Becca Lewis shines as does Foundation Pilates in their presentation of a beautiful clean studio and state of the art equipment. Personable and expert instructors from Becca, Shelby, Beth and Cynthia to comprehensive class offerings of barre jump board or tower make Foundation Pilates the ultimate work out to have you looking and feeling your best by focusing on your core which for me and 2 back injuries that have left me disabled is essential. Thank you to this wonderful team and Becca congratulations you've done an amazing job! read more
