Zaid Hassen

Personal Trainer

My journey began as many have before me: I was a student athlete my entire life and when I reached the age of seventeen I started weight training. I did this to enhance my performance in wrestling and roller hockey. Although my weight training experience was basic, my ultimate goal was to use the knowledge I had at my disposal, to become the best that I could be. Shortly after graduation, about fourteen years ago I joined my first gym here at Signature Fitness expanding my overall focus from muscular endurance to also include muscular development/hypertrophy. That change was a result of becoming a fan of body building of which I now compete nationally and mentor/coach. Over the years, the knowledge that I gained either through study or experience has also helped others reach their personal goals. My training philosophy is rooted in a quote by Henry David Thoreau “There is no knowledge that is not power.” That said, a heavy focus on learning why, is just as important as knowing how.

I have been a personal trainer for close to seven years with a background in bodybuilding style training. I hold a certificate through IFA. In addition, I also am a competitive National-level bodybuilder with the NPC since 2010.

Favorite Shake:
5 weeks out with chocolate, oatmeal, and a muscle building stack.

Favorite quote:
“There is no knowledge that is not power” by Ralph Waldo Emerson.

Favorite body part:

Mornings and evenings Monday-Friday, early afternoon Saturday.

Kenny Reilly

Personal Trainer

I am a certified personal trainer and nutrition specialist. Attending Montclair State University, I received my Bachelor of Science Degree in Health and Physical Education in 2012. Teaching Physical Education full time in East Orange since 2012 has been my main focus but I always train a few older individuals at SigFit to keep my mind and body sharp. Growing up I played soccer, basketball, football and baseball in Lyndhurst and at Queen of Peace High School. My experience consists of working with a wide variety of populations through many different fitness domains including weight loss, strength and conditioning, injury prevention, wellness coaching, nutrition, and endurance training. I believe that a proper balance of resistance training, cardio, and nutrition will simply put your body in better condition overall. Being a trainer for the past 10 years has given me the opportunity to work with many different individuals with fitness goals varying from extreme weight loss(100+lbs) to prepping for bodybuilding shows and everything in between. I enjoy a challenge and love helping people improve their lifestyles mentally and physically.
