Nadia is grateful to be in the business of helping women reach their fitness goals! As co-owner of Body By X, she spent her first few years here managing the business side of things. She watched our trainers change people’s lives and decided she wanted to do the same. Wow is she glad she did! Nadia has helped her clients lose weight, tone muscle and gain strength, others to build stronger bones (via our bioDensity device) and some get a bigger butt (yes, big butts are finally in!). Nadia is encouraging and thoughtful in the custom workouts she creates to help her clients reach their goals.
After nearly 20 years as a personal trainer, and with a nod to his graduate degree in clinical psychology from Pepperdine University, every workout with Charles Walz begins with a simple question, “How do you feel today?” It’s a personal approach designed to not only discover how his clients’ feel physically, but mentally, as well. As Charles explains, “Each workout should not only help strengthen the bodies, but also the minds and spirits of my clients. Discovering, first and foremost, how my clients are feeling helps to set the tone for our time together. We all feel differently each day and I want to ensure that the workouts are tailored for maximum benefit—whether my clients feel great and have their A-Games, or maybe need a bit of a pick-me-up.” Upon this check-in, Charles incorporates flexibility, cardio and muscle strength/endurance to craft a multi-faceted, custom workout that targets each client’s individual goals and objectives. Bringing best practices expertise to his work, Charles is certified as a Personal Trainer from the prestigious American College of Sports Medicine with enhanced certification in Advanced Personal Training and Exercise and the Older Adult. He has also been certified as a Group Instructor for Spinning and TRX and as an Emergency Medical Technician (EMT-I).
Out of the gym, Charles can be found feeding his passion for the backcountry—backpacking, climbing, snowshoeing and/or cross-country skiing. He’s also never one to miss a long motorcycle tour or good live music.
John has been professionally educating, empowering, and coaching clients for over 12 years. He started in the health and fitness field as a personal trainer while attending college where he realized his passion for helping others and transforming clients’ lives.
John's philosophy: “I am an avid learner and I’m always looking to improve and become a more effective teacher and educator. Being a good listener and asking the right questions has enabled me to effectively coach and educate clients while exceeding expectations. There are many challenges you face each and every day, but when you really get down to the heart of the matter...are you growing and learning each day? Are you challenging yourself to your full capability? If you’re not, I suggest you’re stagnant and stagnant means you are unnecessarily suffering. I have committed my life to helping others and empowering clients to improve themselves and their quality of life. We can all make substantial differences and improvements in our lives and in the lives of our families and friends. I help people move and feel better in their everyday life whether that means helping you to remain strong and independent with your life, or incorporating sport specific drills that improve skill levels for your sport of choice. Everyone has their own idea of improving their health and fitness. I promise to listen and design a fitness protocol, or implement a nutritional program that is individualized and effective. I will provide the most comprehensive up to date assessment, evaluation, and fitness practices that are available in the field today."
John founded Personal Training In Marin (PTIM) and regularly blogs fitness tips and wisdom. He is nationally certified by the American College of Sports Medicine as a Health/Fitness Specialist and by the National Strength and Conditioning Association.
