Hello, Welcome to In Form!

ALEXIS AMBRUSO PEÑA LMT, Owner and Pilates Instructor



Hello, I’m Alexis! I’m delighted you’ve found me here. As the founder and owner of In Form Pilates & Bodywork, I’ve been a comprehensively certified Pilates instructor since 2017 and a Licensed Massage Therapist since 2022. My passion lies in movement, and I’m thankful for the opportunity to educate, support, and share Pilates with my clients. My inherent curiosity about the human body has led me to expand my practice into bodywork, enabling me to help my clients find relief and relaxation from everyday stress and chronic pain. I believe that everything is connected, and the more knowledge I gain, the more I can share. My ultimate goal is to help people enhance their daily lives and find joy in their own bodies.

Originally from Newington, CT, I now live in North Austin with my husband and our energetic pup, Mookie. I’ve been dancing since age seven and have had the fortune of being exposed to various somatic practices throughout my training. While in college, I formally studied Pilates and was instantly smitten. It became my go-to-warm-up for classes and performances and played a crucial role in rehabilitating injuries. I’m excited to work with you and share the power of Pilates and bodywork!
