Kelly & Matt

IYF co-founders met at a health club in 1995 and have since lived an active, balanced lifestyle.


The Megyese's feel that a physically and mentally strong foundation is critical for good health and can help with confidence throughout life. After relocating to Phoenix, AZ they started IYF in 2019 to share what they’ve learned about achieving mind and body balance. Rather than starting with their own physical space, Kelly and Matt devised a different business model - IYF is a 'mobile studio' offering online live classes, on-demand videos, fitness gear, and ZYIA Active apparel.

As an advocate for health and wellness, Kelly uses her experience as a fitness instructor to help others achieve their personal goals. She is certified as an American Council on Exercise (ACE) Group Fitness Instructor; Barre Above Instructor; Cycling Fusion Indoor Cycling Instructor; and for CPR/AED through the American Heart Association. Kelly is IYF's trainer - running the class schedule and sessions. 

Matt has always enjoyed running, lifting weights, and boot camp or high-impact exercises. He discovered barre as a way to complement intense workouts then was hooked. He was certified as an American Council on Exercise (ACE) Group Fitness Instructor and for CPR/AED through EMS University, but instead of teaching is a student - feeling the difference IYF classes can make.
