Cathie Apple, NSCA-CPT, has been teaching and training clients and students for nearly 20 years. In that time, she's specialized in yoga, weight lifting, cycling, and CrossFit. She's helped hundreds increase their mobility, cardiovascular health, and functional strength. She is a proponent of a return to natural movement patterns, with a focus on exercises that have immediate practical benefits to everyday quality of life. Her clients receive individualized protocols to address their specific needs and goals.

Using herself as a guinea pig for her training methods, Cathie regularly competes in Olympic-distance triathlons, and has done several marathons, obstacle-course races, a couple of Ironman 70.3 races, some CrossFit team competitions,  and a Ragnar trail relay. Her less-competitive fitness exploits always involve backpacking in the wilderness; her favorite trip being the John Muir Trail.

Cathie is also a professional flutist, a career that often requires sitting in rehearsals for 2-3 hours at a time. The playing position for the flute in particular and its potential for injury drove her desire to research techniques that would prevent injury and enhance her ability to perform.
