Born and Raised in New Brunswick, NJ, Exit 9 off the New Jersey Turnpike and in Loving Memory of my cousin "Eric "E-9" Andrews, birthed my company N9NE Fitness. 

My passion for fitness started in 2007. I began to share my experiences and to motivate others to help achieve their fitness goals. Fitness training is not only my fuel, but my drive to be the best Me. My mission is to continue to share my knowledge and experiences with others, in hopes to help more people over-come self- doubt & self- criticism while making a healthy lifestyle change.

I started working with N9NE  fitness months ago he’s an amazing trainer. We set a goal and he pushed me to get there. In about 8 sessions before reaching my 10th I was down 22 lbs. I’ve recommended him to family and friends if you’re serious about losing toning or maintaining he will definitely keep you focused he’s extremely passionate about his craft and I don’t advise you to start if you aren’t disciplined or serious about making this apart of your lifestyle.
