HIP Studio was born out of a friendship between two women with a love for fit living and high intensity workouts. South Bay locals Christine Crivello and Amber Susa Jewett were bored with traditional gyms and tired of having multiple memberships for specialty classes to get the workout they wanted. They shared a vision of creating a space with a true sense of community that had something for everyone and where fitness and health become a priority. Together with their unique backgrounds, they opened HIP to give clients workouts that are fun, effective and results-driven. As instructors themselves, Christine and Amber understand how valuable it is to have amazing trainers with the perfect blend of knowledge, passion and experience. Every trainer at HIP has 8 years or more experience and truly love what they do. You will find trainers that care and continuously push you to the next level.

'HIP Studio isn’t just a place to workout; it becomes a lifestyle for our clients. When you walk though our doors you will feel the energy and passion for fit living. We like to have fun while making health and fitness a priority. We're about feeling your best and being YOUR best!'
- Christine & Amber

Christine Crivello Bartolomasi 

After years in sales and marketing in the music and fashion industries, Christine was ready for a change. Taking a Pilates class on a whim, she had no idea what it would eventually lead to. After a few classes, she was hooked and so inspired that she decided to get her PIlates certification thru BASI in 2010. That same year, she met Amber and the two opened HIP to bring their passion for teaching and workouts they love to The South Bay. Christine loves motivating clients and teaches them to move with purpose and control, giving them awareness that will reshape their body. When she is not teaching, she is working on new recipes and meal plans for The HIP90 Nutrtion Plan. She avoids fads and shows clients how to eat real food. She is certified in Pre & Post-Natal Pilates, TRX and is working on her Advanced Pilates certification with Vital Balance Pilates.
