"Kathleen is a fabulous trainer. She is knowledgable, responsive and pays attention to your needs so that she can guide you correctly. She knows how to push you while keeping you safe and comfortable so that you can achieve your goals. I love how Kathleen "gets" me—she understands my challenges and helps to figure out a way around them. She's smart, funny, and fearless. I am so appreciative of how she keeps me motivated and making me want to come back for more!" ~ Mayumi, Seattle

“Kathleen is an attentive, knowledgeable, and compassionate kettlebell instructor whose enthusiasm energizes those around her. She delivers quality instruction with cheerful wit and provides targeted, easy to understand feedback that produces quick results for all levels of kettlebell practitioners. Kathleen creates a collaborative, yet challenging workout environment that makes people want to sweat it out and come back for seconds.. or thirds.”~ Thomas, Seattle


"You get the full package in Kathleen Chandler. Capable instruction with an eagle eye on safe and proper form. Strenuous workout design that leaves everyone from novices to jocks in a pool of sweat. Sensitivity to clients' needs and goals. And an engaging personality with a great laugh and warm smile!"~ Gena, Seattle


"I have been a Kettlebility member for 2.5 years, and Kathleen has been an integral component of my success in taking on kettlebells as a training format. Training with Kathleen has greatly improved my performance in my half-marathon and triathlon races. She is a very approachable trainer with a great balance between being supportive and giving some "tough love" to help me push past my comfort zone and become stronger and more balanced as an athlete. She focuses on form and safety rather than speed and reps, and brings a lot of fun and energy to class - which is a great thing, because the laughter and support helps me to get through her classes, which are tough and a great workout. She's also great at providing excellent nutritional advice and, when I'm traveling for work, solid workouts that I can do anywhere without having to travel with a kettlebell."~ Karen, Seattle


"Kathleen was my very first Kettlebility instructor, and her fun, high-energy classes have helped me to become strong beyond my expectations. She keeps her students moving with a personable and encouraging yet challenging style of instruction. A knowledgeable, safety conscious and watchful trainer, she is precise with instructions and corrections, and I love her choice of techniques and the balanced way she constructs her workouts. Plus she makes us laugh. Thanks for the pushups and the slider abs, Kathleen…you rock!"~ Mary, Seattle


"I truly appreciate Kathleen’s ability to provide individual attention even in a group setting.  She is able to break down the series of movements required in a way that is very helpful and useful, while offering lots of positive feedback in a fun and constructive environment."~ Janet, Seattle
