I have been working as a Personal Trainer, Barre and Pilates Instructor for many years and have certifications from national groups including the American Council on Exercise, the Pilates Method Alliance, Stott Pilates, Booty Barre and more. I did my training through Black Rock Pilates (Balanced Body). I love to help pregnant women to feel strong and help with pelvic floor issues and diastasis recti. I'm Leslie Caney Berni
I love to teach Pilates mat and appratus. It helps with core strength, especially. I work with men and women of all ages to get their bodies back. I'm an excellent trainer and Pilates instructor. I'm PMA certified and certified through ACE, Booty Barre, TRX, Training for Warriors and Total Barre. I teach in Stamford and have clients from North Stamford, Pound Ridge, New Canaan, Darien and Greenwich. I have taught at many Pilates and fitness studios and gyms, including the New Canaan YMCA, Halo Studios, Inspire Fitness and more. I have a beautiful Covid-safe Pilates studio and I love my clients of all ages and abilities.

I am a passionate professional, with a lifetime of experience in dance, gymnastics, yoga, Pilates and sports/fitness conditioning. In private sessions, duets and group classes, I love to work with all levels and ages to create customized, challenging--but fun--progressive Pilates and exercise programs. I take a holistic approach, grounded in the latest exercise science, which will help you to feel fit and fulfilled—body, mind and soul. Fitness is an ever-adapting journey, not a destination. And it's for life. My goal is to help guide you on that journey, in and outside of the studio.
