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.

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.

Ricardo Alves

Personal Trainer

My passion for fitness began the same way as many other fitness enthusiasts. I was an athlete in high school, played soccer for four years and began training during that journey in order to progress and improve myself. Beginning of Freshman year of high school, I knew nothing when it came to weight training. Our head coach would force us to train in the school weight room during the winter to become physically prepared for the upcoming season. His decision to have us weight train was one of the greatest things to ever happen to me. It opened up my eyes to how wonderful training is and how much it benefits you. I began to become more committed during Sophomore year and during my Junior year of high school, a friend of mine recommended me to join Signature Fitness. At the time, I was going to a smaller gym in my town, but once I gave Signature a chance, I never looked back. As of now, I’ve been coming here for six years and enjoy every day spent working out. After high school, I decided to stop pursuing soccer and put all my focus into muscular training to look and feel the best I could be. People would often ask me for advice when it came to training and dieting which influenced me to perhaps do this as a profession because it grants me the opportunity to change someone’s life for the better. My desire to help people with their fitness goals is what ultimately led me to become a personal trainer.

Background: I am NCEP Certified, currently pursuing a certification through NASM. Looking to pursue a Bachelor’s in Nutrition and Exercise Science.
