About Zachary

About me: I am an expert in helping individuals reach their fitness goals. I specialize in helping my clients look and feel better, grow muscle, lose fat and improve their quality of living. My fitness journey: Like many others, my personal training journey started with my own training. As i graduated high school i slowly became increasingly out-of-shape. I was unhappy with how my body looked and how i felt physically. For years i struggled to find a diet and training regimen that worked and that i could stick to. I helplessly lost a few pounds of fat only to gain more than when i started. The excess amount of information on-line made the endeavor seem impossible. Nonetheless i had a goal, so my unyielding perseverance drove me to dig my heels in and incessantly research how to train my body and how to eat to achieve my goals. Through trial and error and constant second guessing i succeeded and lost over 45 lbs. of fat. From this journey my profound love for health, fitness, nutrition, and exercise science was born. Since then i have competed in kickboxing as well as powerlifting and became a personal trainer! I have been informally training clients for about 2 years now and formally for less than a year. I have been training myself for roughly 5 years. Typical Session: On our first session we will discuss your prior training experience and your training goals. I will briefly assess your physical standings and we will then discuss a plan and get to work. i mostly meet clients in corporate gyms(You Fit, La Fitness etc.), but also in their homes as well as public parks depending on their training goals and status. It is my goal to give clients the knowledge and motivation they need to eventually be able to do most or all of their training without a trainer.
