Move better,
for life.
Campbell’s original Pilates and GYROTONIC® studio. Since 2001, Chris and Sonia Lopez have helped adults over 40 build strength, restore ease, and get back to the things they love.
FOR YOUR BODY NOWEvery new student starts one-on-one, so we learn who you are, where you want to go, and build a plan to get you there.
SMALL BY DESIGNMOVE classes hold four people. You are never lost in a crowd.
BUILT FOR REAL LIFETrain so that daily movement, travel, golf, dance, and active aging feel better.

Two methods, one aim: a body that moves the way you want it to

Pilates
Controlled, precise work on the Reformer, Cadillac, and Chair that builds deep core strength, better posture, and balanced, efficient movement. We teach the Contrology method, the original work of Joseph Pilates, adapted to your body.
What is Pilates
The GYROTONIC® Method
Circular, spiralling movement on specialised wooden equipment that opens the joints, decompresses the spine, and ties movement to breath. Students call it a workout, a stretch, and a reset at once.
What is the GYROTONIC® Method
Same two teachers, same studio, since 2001
Chris and Sonia Lopez opened Body Evolutions in Campbell in January 2001 and have taught here every week since. Thousands of students have come through the door, many of them still training with us years later.
Sonia is known for detailed, gentle instruction and works often with injuries, scoliosis, and post-rehab movement. Chris, a GYROTONIC® and Pilates trainer for over 24 years, helps active adults ease back pain and keep doing the activities they love.
Small by design, for adults over 40
We are not a gym. Private sessions, duets, and four-person MOVE classes mean an instructor sees every rep and can adjust it for your history, your limits, and your goals.
Students come to us to ease chronic back pain, recover from injury, keep golfing or dancing into their seventies, or simply feel at home in their own body again. Many of them travel here from San Jose, Willow Glen, Los Gatos, Cupertino, and Santa Clara.

“Therapy for your body. Longevity for your future. Community for your soul.”
The idea we opened with in 2001What our students say
Back pain and stiffness
Clients often arrive after trying to solve stiffness, pain, or postural patterns elsewhere. The work starts with how they move today.
“I highly recommend Chris and Sonia at Body Evolutions. I went in out of shape and with little to no strength in my body. I’d never done Pilates before and it took me a while to get comfortable. After Chris’ patience and our work together, my back no longer hurts, I am more flexible and I am much stronger.”
Tricia B. Google reviewLiving well with scoliosis
Scoliosis asks for steady, specific work rather than a general class: length, core strength, and a new awareness of how you carry yourself.
“Sonia has been a godsend in helping me manage my scoliosis. She has helped me become more flexible, strengthen my core and improve my posture. I’m much more aware of how I move now, and I often hear her voice telling me to ‘grow taller’ — so I do!”
Barbara K. Google reviewStarting from any fitness level
Walking into a studio is daunting when you are not sure you are fit enough for it. Sessions begin where you are, in a room where nobody is measuring you against anyone else.
“Sonia is a great teacher. She knows her stuff and is always working to expand her knowledge. She teaches in a non-judgmental way that makes everyone feel comfortable, regardless of their fitness level. Body Evolutions is a community place. You can feel the camaraderie.”
Nancy C. Google reviewRebuilding strength after childbirth
Pregnancy and birth can leave the back sore and the core unsure of itself. Gentle, detailed work restores the strength that ordinary days ask for.
“Through her gentle and detailed sessions, Sonia gave me back my normal life and more strength. After COVID, my now teenager daughter and I are back in the studio to get stronger together. I cannot recommend Sonia enough for all levels of fitness.”
Rieko N. Google reviewStill dancing in your later years
Many students arrive sure the thing they love is behind them. Private sessions go straight at the strength and mobility that keeps it going.
“As an ‘older’ person I figured my dancing was coming to an end. After starting private sessions at Body Evolutions my dancing has gotten better and I can move better than some much younger dancers in my class. Their sessions are as vital to me as eating a healthy diet and getting a good night sleep.”
Sharon W. Yelp reviewGolf and a body that will not open up
Sport-specific tightness quietly limits your swing and your comfort. A targeted stretch and mobility plan gives that range back.
“Great to work with Sonia! Coming from a golf background, I’ve experienced the best stretch ever. Highly recommend Body Evolutions Fitness.”
Tammy L. Yelp reviewSessions that never get boring
Repetition is why most people stop training. Programs change as you progress, so the work stays interesting and keeps producing results.
“Sonia and Chris are fabulous trainers and take professional pride in their work. They vary the routines, so it’s never boring.”
Wendy G. Studio reviewFewer trips to the chiropractor
When pain keeps sending you back for treatment, the pattern underneath it is usually how you move. Training that pattern is what makes the relief hold.
“Sonia is very caring and works with you right where you are at to achieve your goals, but she works you hard! I have gone less to the chiropractor since I started seeing her. I highly recommend this studio!”
Kristina P. Yelp reviewRange of motion for everyday life
Stiffness shows up first in the ordinary things: reaching, bending, turning to look behind you. Flexibility work hands those movements back.
“I’ve experienced dramatic improvement in my range of motion. The benefits of flexibility in everyday life has been life changing.”
Sam K. Studio reviewComing back from surgery or injury
Rebuilding after an operation or an injury needs someone who knows what to load and what to leave alone. Each session is built around the body in front of them.
“Sonia is an excellent Pilates instructor. She is very knowledgeable about the human body. If you are having problems from operations or injuries, she knows what to work on to get you feeling better. I walk into the studio and walk out after my session always feeling better.”
Phil V. Google reviewFeeling at home in your own body
Some students arrive braced, guarding one side, holding themselves together. Balanced, supported movement lets the body settle and carry itself again.
“I feel amazing right now. I’m walking around and my side isn’t collapsing. I feel so comfortable in my body. Thanks so much.”
Amy P. Studio reviewUndivided attention, every session
In a busy gym you end up correcting yourself. Here one instructor stays with you the whole way through and adjusts the work as you go.
“Chris and Sonia give their undivided attention to each student, each session, the whole way through, and bring lovely energy to their work.”
Terri Q. Studio reviewBack pain from carrying small children
Years of lifting toddlers leave the back paying for it long afterwards. Retraining how you load and move is what stops the flare-ups returning.
“The episodes of back pain I suffered as a young mom due to lifting my small kids completely resolved after I started classes at Body Evolutions over 10 years ago. The classes have also worked wonders on my posture and flexibility. Sonia is a master teacher, detail oriented, precise and devoted to maximizing the benefits of the Pilates training.”
Iliana S. Google reviewA session matched to the day you are having
Some days you arrive fresh and some days sore. The work is adjusted on the spot, so you keep progressing either way.
“Chris has been my Pilates instructor on a weekly basis for over a year. He’s been great from the beginning. I enjoy how he customizes my workout based on how I’m feeling that day, while also pushing me to keep getting better. It’s a good balance. Chris is very knowledgeable, patient and fun to work with.”
Terry T. Google reviewCompletely new to Pilates
Most people start here with no experience at all. You are welcomed, taught slowly, and given homework that holds the progress between sessions.
“A true novice to Pilates when I showed up, I felt welcomed from the beginning. Their patience and encouragement have allowed me to become physically stronger and gain greater mobility over the last year. I get a great workout during my sessions, and the homework helps me between sessions. This almost 60 year old loves Pilates!”
Lou A. Google reviewStarting in your seventies
Age is far less of a barrier than people expect. The work begins with the body you have now and builds from there.
“I started three years ago at age 70 — proof that Pilates is for all ages. I’ve never been stronger! Going to Body Evolutions is like visiting a family, one that understands you, knows your aches and pains and knows your physical strengths and weaknesses.”
Kathleen D. Google reviewAching joints, shoulders, and neck
Chronic aches usually trace back to how the body is loaded all day. Regular, guided movement changes that load, and the pain follows.
“I started having issues with my joints recently and wanted to start a regular exercise routine. I never tried Pilates before, but this studio had amazing reviews, so I gave it a shot. My joint pains are gone. The chronic pain I had with my shoulder and neck got significantly improved after I started Pilates.”
