  • John Snow


    John Snow is a boxing trainer/personal development coach with over 20 years experience. Born and raised in Brooklyn, John's life changed when he gathered the courage to climb the stairs of the famed Gramercy Gym near Union Square. It was there that he began the never-ending journey called boxing. Through the various stages and challenges of life, he realized that the one thing that helped frame his success was what he learned about himself while boxing.

    Unfortunately, most people boxing today miss the most important component of the sport—that is ,the mental training required to win and the relationship between fighter and trainer. It is this training that is so valuable to children and teens. Regardless of their athletic ability, boxing, when taught properly, will develop a strong sense of self confidence, discipline, and self reliance that children will be able to utilize both in school and everyday life.

    John is a graduate of Fordham University as well as a CPT with the National Academy of Sports Medicine. He is most proud of his role as a father to his 13 year-old son.

  • John Venditti

    NASM Personal Trainer, Youth Exercise Specialist, Strength Training and Sports Skills

    I believe the best time to start practicing fitness and health was yesterday. The second best time is today.

    No matter what age - young or old - I enjoy helping enrich and change lives through training. Since being diagnosed with Type 1 Diabetes as a teen, I decided to take action about how I wanted the rest of my life to be - long, healthy and joyful. I took up training and quickly realized my calling was not just to train myself, but others as well. From being a summer camp counselor in my high school years to formally training teens now, I have always enjoyed working with kids and young adults. It is never too early to learn good movement "habits," and stay ahead of the curve with sports performance and strength.

    I am currently certified by NASM and am pursuing a Doctorate of Physical Therapy. I emphasize correct, efficient movement that transfers over to sports, daily life, and addresses stability and strength. I am well versed in many modalities and enjoy being creative with whatever equipment is available. Most of all, I enjoy making workouts fun, challenging and engaging!
