Preston Grayem

Fitness Coach

Preston was born and raised in a small town in So-Cal. As a child, he played sports year-round, eventually finding his love for baseball. In high school, he sustained a serious injury in his throwing arm from years of abuse and improper training. His baseball career ended, but his love for health and fitness began.

Preston went on to a Junior College where he narrowed his interest into Kinesiology. From there he attended CSUSB University and finished his degree in Kinesiology with a concentration in Exercise Science, while working as a trainer and lecturer to fellow students. This deep dive into Physiology and Biomechanics allows him to have a better understanding of why we move and how we move- so he may safely and effectively instruct others on new movements or improve familiar ones. Being an athlete, he knows what it’s like to fight for the leading edge and is an educator at heart who wants to teach others how to manage their own health or guide athletes to the next level.

Beyond The Gym

    • Let’s get Real. What is your largest health and fitness thorn? How do you prune this thorn?

      Even as a professional in the industry, sometimes it is hard to stay consistent with an Exercise routine. For me personally, consistency with a specific program is the most difficult aspect. There are so many ways to get in a workout and a plethora of fun exercises to do. A way of narrowing down my focus, I write down exactly what I will do that month prior to it starting. This allows me to hold myself accountable. The plan has been set up already, it would therefore be more work to stray from it than to stick with it.

    • Results matter Most. Why are you a Personal Trainer? What motivates you to Coach people?

      I believe it is the duty of every individual to share their gifts with others. My gift is the ability to teach. With that in mind, I have chosen to teach health and wellness. Using my gift to spread my passion allows me to help those around me with the greatest amount of effectiveness. I love to coach because it allows me to be the support someone needs. Need to add tools to your toolbox? I can help with that. Need someone to hold you accountable each week? I can help with that. Need someone there who you can connect with and make it more than just a workout? I am there for that.

    • Education is Success. How are you better than all the other personal trainers? What makes your Coaching different?

      I am voraciously curious. This has made me into a lifelong learner who will never stop seeking out more information. Therefore, I will do my absolute best to bring to every session the most recent research and information. I also consider all types of training as having the possibility of being legitimate. If it fits my Three requirements, I will consider it. It must be safe, challenging and fun.

    • Are you human? Who are you outside of the Gym? What are some of your hobbies you enjoy?

      Sometimes people ask me if I am human, but I am not sure. What is human? That I don’t know either. What I do know is a do thing outside of the Gym that aren’t working out. Those include hanging out with my beautiful Wife Onyx or my precious daughter Saoirse. They are my everything. As for hobbies, I have quite a few. I enjoy learning new things whenever I can and getting out into nature as often as possible. Indoor activities include reading, poetry, video games, board games and Dungeons and Dragons when I can. Outdoor hobby would be all the normal ones, hiking, camping, swimming, kayaking and most of all Traditional Archery.

    • You’re my People. When is the best time to connect with you? How do you like to meet new clients/friends?

      I am best reached at the Front Desk of Jack City Fitness between 10am and 5pm Monday through Friday. I prefer to meet in-person. Over the phone, text or email will work in a pinch, but I love to be social and interact in-person with everyone that walks through that door! If you have some time and want to drop in for a quick chat and a tour, please do so!
