Emily Knowles

Group fitness and Pilates instructor, CPT, Les Mills instructor, WNBF Masters Pro

Emily has been working in the fitness industry since 1997. She brings expertise in certified personal training, group fitness, and Pilates instruction to PeakFit with passion. A long-time staple of the greater Sun Valley area, she is known for her expertise in training and pilates instruction, her infectious energy, her consistent pursuit of knowledge around health and wellness for all clients, and her energetic spirit.

Originally starting with teaching group fitness, she quickly crossed a few things off her “bucket list” including her first bodybuilding competition and marathon. She fell in love with all aspects of fitness, studied, and tested to get her personal training certification in 1999. Then she went on to acquire her Classical Pilates certification in 2003, apprenticing 600 hours and testing with Romana Kryzanowska, protégé of Joseph Pilates.

She continued on to become certified in multiple Les Mills programs - BodyPump, CORE, and BodyFlow. Emily’s love for health and fitness radiates in her training and her goal is to share that with her clients, helping them adopt and maintain healthy lifelong habits.


Competing 13 times and still counting, in natural bodybuilding, Emily earned her Pro status in the WNBF in 2021 and won first place in WNBF Worlds in Las Vegas. Born and raised in Washington, but a Wood River Valley resident since 1997, Emily has been a familiar face and staple of our community. Currently a local lululemon ambassador, she does it all while being a devoted wife, mother, dog owner, and community advocate.
