Ariana opened Core Effects Personal Training in January 2011, training local and mobile clients around the Northern Virginia area. 

 As an ACSM Certified Personal Trainer and American Red Cross Certified Water Safety Instructor, Ariana works with clients to create unique and effective training programs that inspire long term, healthy lifestyle patterns.  As a previously certified Emergency Medical Technician, Ariana has the knowledge and experience to safely train clients with a variety of health issues and injuries. 

“Becoming a personal trainer has been the most fulfilling and rewarding choice I have ever made. I absolutely love what I do as a trainer, not just because I am pushing each individual to their maximum potential, but because I am an educator in the fitness field. I challenge myself  to learn more about physical fitness, nutrition and sports medicine everyday to be the best personal trainer and educator that I can be for every client and my own fitness goals.”     -Ariana Leonard
