San Diego's Premier Full Service Pilates Studio




PilatesRx is San Diego’s premier, full service Pilates and body conditioning studio. 

As a fully-equipped studio, we specialize in post-rehabilitative programs, strength and flexibility conditioning, sport-specific training, and both pre- and post-natal Pilates.

Our specialized sessions and classes combine contemporary mat and equipment based Pilates exercises with rehabilitative and corrective movement patterns. Our certified trainers offer expert instruction to guide you through low-impact movements designed to increase body awareness and improve postural alignment.

PilatesRx general and sport-specific body conditioning programs are beneficial for pain management and injury prevention. Pilates and functional movement training will help clients discover their spine, core, and pelvic floor. These programs are suggested for athletes of all competitive levels including, but not limited to, football players, baseball players, soccer players, lacrosse players, golfers, swimmers, runners, cyclists, equestrian riders, dancers, gymnasts, skaters, and climbers. People of all walks of life and ages can experience an increase in mobility, stability, and power for enhanced quality of movement and life.

PilatesRx connects with your obstetrician for the management of pre- and post-natal Pilates programs. Specialized programs keep mother and baby safe during the vital stages of pregnancy, labor, and post-natal recovery. Pregnancy often presents challenges such as low back discomfort, sciatica, sleep disturbances, and nausea. Pilates increases pelvic floor strength, builds hip stability, heightens core awareness, enhances breathing flow, and reduces stress. PilatesRx mothers experience easier pregnancies, faster deliveries, and even speedier recoveries.

PilatesRx post-rehabilitative programs are ideal for those seeking additional care, after completing medically advised physical therapy, for the management of their injuries, musculoskeletal disorders, and/or diseases. Recovery can be greatly enhanced with a proper rehabilitative program that addresses special needs or concerns. Those suffering from musculoskeletal or neurological disorders can experience an increase in body awareness, balance, and overall stability.

Our post-rehabilitative programs are complemented by our in-house physical therapist Nathan Briner, Owner of True Balance Sports Therapy Clinic.

A Message From the Owner

I would like to share my biggest goal for PilatesRx: Community. I want each one of our clients to know they have a network of people that cares about their health and wellness. Each session and class is designed to help clients reach their mind-body goals. PilatesRx is an environment built on understanding, compassion, and dedication to helping clients discover pain-free movement. It brings me great joy to see clients find their inner and outer strength. Join our community and awaken your new life.





Private and Semi Private Sessions are personalized to help you meet your health and wellness goals. Each 55-minute session will highlight corrective movements, pain reduction, and both strength and balance exercises.

Mahlia grew up in San Diego, where she was introduced to Pilates at an early age after sustaining sports-related injuries. She continued to feel the first-hand benefits of Pilates while studying at University of California Irvine. Mahlia believes in the combination of mindful breathing and corrective movements to improve both physical and mental health.
When not in the studio, Mahlia loves spending time with her family: Roark and Hemingway (studio Basset Hounds) and Steve, (PilatesRx legal business manager). You can typically find her on the golf course or at the dog park.

Christi Wilson

Christi Wilson is a STOTT certified Pilates instructor with continuing education in the MELT Method, TRX System, and Body Arts and Science International education focusing on functional movement with an emphasis on osteo-based Pilates.  While her approach to Pilates is athletic-based, her philosophy is mindful movement with awareness of building strength and mobile integrity from the inside, out.

After the birth of her two children, Christi became a commited student of Pilates to maintain health, strength, and movement to keep up with her family's  (now soon to be teenagers) active lifestyle. As a graduate from San Diego State University, she fell in love with San Diego and never left.  When she is not at the studio, you can find her running around Mission Bay, surfing with her family, mountain biking, and taking full advantage of the Southern California lifestyle.

Nathan Briner

Nathan Briner, Owner of the TrueBalance Sports Therapy Clinic, had spent the past 20 years utilizing neuroscience and pain education, combined with manual and movement therapies, for the treatment of chronic pain, muscle, and joint issues.
His overarching goal is the transformation of the outdated, misinformed culture surrounding pain toward personal empowerment and exquisite appreciation of our physical bodies. He spends half his week as the fitness manager at Rancho La Puerta in Tecate, Mexico weaving therapeutic concepts into his yoga, Pilates, and posture therapy classes. Nathan also lectures and conducts workshops on posture therapy and pain neutralization techniques.


truebalance sports clinic

The TrueBalance Sports Therapy clinic offers one-on-one sessions for chronic pain, recent injuries, back spasms, sports performance and more. We use hands-on techniques that neutralize painful trigger points, promote needed blood flow and help recover unguarded movement. Our sessions are very personalized. We spend up to an hour per session to ensure you have received the care you need. All corrective exercises and movements are designed around your capability, comfort and your schedule. We make sure that you have been heard and everything from your specific pain complaint, your lifestyle and your goals are taken into consideration.

Every session includes:

  • Therapeutic education so that you understand your pain. 
  • Pain free hands-on therapy called DermoNeuroModulation to eliminate painful muscle spasms if necessary. 
  • Movement coaching and corrective exercises as needed. 
  • Personal coaching for daily activity modifications with respect to your pain.

At the TrueBalance Sports Therapy Clinic we see significant to complete improvement in no more than four visits for a particular pain complaint. If we cannot produce noticeable progress in two sessions then it's possible that our program may not be for you and we can refer you to other specialists. We have seen some issues resolve in as little as one session and some that have taken more than four but we always discuss what to expect and progress with you as a team. To help you continue toward greater strength and confidence we encourage you to work with our PilatesRx team. We communicate your particular needs with the instructors so that they can build a fun and effective movement program for you.
