FLEXX Studios Burlingame


Owner / Manager

Hello, and welcome to the day you discovered a fitness solution that changes your life. My name is Annabelle, and I’m a wife, mama of two and a former financial services exec who’s always had a passion around fitness as a lifestyle. I wanted to create something that was unique from all the studios I’ve attended over the years, something that not only would provide amazing workouts, but a sense of community, serenity and a place everyone would look forward to coming to. I wanted this studio to be what our clients look forward to the most in their day, where they check everything at the door and are greeted with smiles, get an amazing workout and leave feeling like they are on top of the world!


We are a one-stop shop for core AND cardio (Reformer Pilates, TRX, Kickboxing, Strength Training, Bootcamp, Yoga, Cardio Barre & more!). FLEXX Studios is the place that will give you the variety you need to maximize your time, money and fitness goals! Welcome to our FLEXXfam!

Trainer / Instructor

Caroline is a NASM certified fitness professional and all-around athlete (specializing in boxing and basketball!) with a passion for helping people believe in themselves to push past their limits. She believes the key to a long-lasting relationship with fitness is a motivating community and a desire to continually challenge yourself and learn new skills. Her love for fitness started with basketball at a very young age (a sport she still plays to this day!). After an ACL tear during her last basketball season, the intense physical therapy inspired a fascination with biomechanics — and just the amazing ways our bodies can move. The rest is history! From HIIT training to strength, to boxing, barre, and dance parties in her living room, Caroline loves to challenge herself and have fun! Ultimately, she wants to help people find joy in the exploration of movement to keep strong, healthy and happy.

Trainer / Instructor

Eddie Erfe,  BASI Pilates instructor. Her background stems from Aerial Suspension, Fitness, Yoga and Martial Arts.

Eddie's philosophy is that movement results in one being able to move better whatever the end goal might be. She considers it a great opportunity to share, with those who seek to learn more about their bodies, while developing themselves to become more fit and better for it. When away from the movement arts, she is an outdoor enthusiast, an adventure and joy seeker when out traveling.




Leah is a seasoned group fitness instructor specializing in cardio kickboxing. Her fitness journey started 20 years ago when her and her daughter enrolled in karate classes just for fun. Martial arts has since become a passion and a lifelong journey for Leah. She subsequently started teaching kickboxing at the dojo and became Tae Bo® Certified under Billy Blanks. Over the years, she honed her skills in boxing techniques, cardio and strength exercises (including HIIT and boot camp style conditioning). Leah also holds the rank of Sandan (3rd degree black belt) in Shorin-ryu karate.

Through years of physical training, certification classes and personal education, Leah has come to understand body dynamics and efficiency of movement. She believes life is about making the most of the present, so when you come in to train she makes sure your time is well spent!

Physical training has changed Leah's life for the better so it is so rewarding to be able to share these joys with everyone at FLEXX, either as an instructor or in class with you. Leah is personally invested in seeing each one of you reach your fitness goals.




My name is Nerrisa Lu and I am a group fitness instructor specializing in reformer pilates.

I began my fitness journey 10 years ago, searching for a perfect workout that can accommodate my heart condition (HCM). I became a instructor in 2018. I taught weekly classes up until my heart transplant in June 2020. Thankfully with all of my pilates training, I recovered quickly and was able to get back to teaching in July 2021. I want to use the experience and skills I have to help clients have a stronger, healthier, and happier life.

I couldn't be happier to be a part of the FLEXX Team and Community! I look forward to FLEXXing with you in class!
