These sessions are designed to work your muscles to fatigue, combining sculpting moves with cardio intervals to build strength and increase your metabolism for a full-body workout in under an hour.

★ 5★ 4★ 3★ 2★ 1Inviting and inclusive environment for trying Reformer Pilates for my first time. I really enjoyed the initial private introductory lesson, so I was comfortable using the machine before starting classes. Alyson is kind and just the kind of instructor I was looking for! A boutique individualized workout experience that has been wonderful so far.
September 10 · Elizabeth DonelsonGreat place! Coming off a knee replacement and having a shoulder one done soon. Allison was extremely knowledgeable and she helped me with all of the modifications in needed! Highly recommend!
September 10 · Kelly FrelichI thoroughly enjoyed my first Pilates class with Alyson. I love that the first session can be a private introductory class instead of a group setting; that helped me feel very comfortable. Given the fact that it’s been awhile since I’ve worked out, I didn’t feel like I couldn’t handle the class. Alyson pushed me but not to the point where I felt I couldn’t keep up. I will be joining as a member!
April 07 · Aaries BoyerI’ve attended a couple of classes here, and Alyson has been fantastic! She’s knowledgeable, patient, and really focuses on helping you with proper form. The studio is clean and welcoming, making it easy to feel comfortable. I’d definitely recommend it for anyone looking to get into Pilates or improve their practice!
September 19 · Ava WangI tried the reformer for my first time at Infinity Fitness with owner and teacher Alyson Domoto. It was PHENOMENAL! I worked muscles I never even knew I had, and Alyson teaches for all levels. Even as a beginner I was able to follow along, and she gave more difficult options for the advanced students too. The studio is beautiful, and importantly it's IMMACULATE, and additional precautions have been instituted to keep everyone safe from COVID 19, e.g., UV lights after each class, reduced class sizes, disinfecting between classes and masks of course. More information is listed on the website. There are also great introductory options. I highly highly recommend checking out a class!
