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.
