Debbie Warren, Strong to the Core Pilates


Owner & Instructor

Hello and thank you for visiting!  Pilates has changed my life and in that process, I developed a passion for Pilates. A passion not only doing Pilates, but a passion to share Pilates with as many others as I can.   

As I began my formal training, (which honestly will never end), where I was working shut down without any advance notice. It was a situation where the out of town owner just decided to close and overnight I had no place to continue working with my clients. I immediately started working on plans to open my own studio, and Strong to the Core Pilates was created.  I have since relocated to Friday Harbor on the beautiful San Juan Island in Washington and have opened up Strong to the Core Pilates LLC at 140-B First Street, Friday Harbor, WA, 98250.

“Pilates develops the body uniformly, corrects wrong postures, restores physical vitality, invigorates the mind, elevates the spirit” ~ Joseph Pilates 

I realized very early on that my passion for Pilates,  really awakens when I am working with individual clients, vs in a group class setting. We are all individuals with individual needs, individual strengths (or injuries), and individual goals and/or objectives.   The Pilates Method has over 500 exercises. Private Pilates sessions allow focused exercises that align with an individual’s needs, strengths (or injuries), and goals and/or objectives.  It’s 55 minutes out of your day that is focused on your overall well being, so that the other 23 hours and 5 minutes of that day, can be the absolute best.  And soon every day becomes noticeably improved in ways such as you noticing that you have a stronger core or powerhouse, or perhaps you become aware of changes in your ability to move around in however your typical day goes (walking, gardening, sports, breathing), and then when you start to feel as you are lengthening not only your spine but from your toes all the way to the crown of your head.  

I am very excited to be here in Friday Harbor, and I would love to work with you to improve your body and overall well-being.  

I am looking forward to connecting with you ~ Debbie
