Are you up to the CHALLENGE?

Welcome to Challenge Fit AZ, the in-home, near home, and live online personal training service based in the East Valley of Phoenix, AZ.  Hello!  My name is Sean Neff and I am a Master Health and Wellness Coach and have been a professional personal trainer for over fifteen years.  Having recently moved with my family to the Phoenix/Gilbert area I look forward to providing new clients like you with the same quality of service that I have provided to hundreds of clients in the past.  For more than a decade, I have worked with my clients at home, at their business, or in third-party locations (either indoors or outdoors) while providing custom private or semi-private personal training sessions. 

In addition, my partners and I can provide you with quality nutritional guidance.  We are experts at giving you just the right amount of challenge needed to reach your health and fitness goals!

With so many gym memberships sitting idle in the hands of well-meaning folks we asked ourselves what is the number one reason why these ladies and gentlemen aren't making good use of said memberships.  It is not because they choose to not live healthy lifestyles.  Many of them do their best to eat well and move their bodies when they can.  It is not because they do not want to be in better shape and to be able to be as physically excellent as they can be.  This is the main reason why many of these people signed up for a gym membership in the first place.  What we at Challenge Fit AZ have found to be the number one reason for these unfulfilled (yet fully paid for) gym memberships is a lack of convenience... to the clients' a) locations and b) compressed time schedules.  Also, there are those days in the Arizona summers where folks would rather just not leave the house.


With door to door service, we attempt to make staying fit and living a healthier lifestyle much more convenient for our clients.  We excel at bringing top-level knowledge, experience, and certified service to your home or to the parks and beaches near your home.  We love to bring the best out of you with your best schedule and location in mind.  Welcome aboard and we are so glad that you are interested in taking on the CHALLENGE!
