OUR TEAM OF PERSONAL TRAINERS IN East Bay & Tri-Valley, CA

GYMGUYZ Owner – here to remove roadblocks for my team.

My name is Chelsie, I’m a Certified Personal Trainer and Group Fitness Instructor with a true passion for helping people transform their health from the inside out. My journey in fitness began 14 years ago with my own transformation, losing over 100 lbs through training, nutrition, and consistency. That experience didn’t just change my body; it changed my purpose. For the past several years, I’ve worked hands-on with clients of all ages and fitness levels, including weightloss, beginners building confidence in their ability to workout, and individuals aiming to improve mobility and functional strength. I take pride in creating individualized programs that are challenging, sustainable, and realistic for each client’s lifestyle. My coaching style is supportive, encouraging, and focused on longterm success. I believe fitness should feel empowering not intimidating and my goal is to help every client build strength, confidence, and habits that last. Along with my ACE certifications in Personal Training and Group Fitness, I am CPR/AED certified and dedicated to continuous learning in mobility, strength training, functional movement, and nutrition. Whether working one-on-one or leading groups, I bring energy, compassion, and a results driven approach to every session.
