Do you wake up every morning not feeling rested, refreshed, or ready for a day of work and life in general? Do you wonder why is it that some people seem to have the energy and attitude that sustains them throughout the day?

Are you looking to improve the quality of your life through fitness?

I have spent a lifetime asking these same questions, and over the years I’ve learned that there is no magic bullet, pill, or quick fix.  I spent my 20 years sitting behind a desk gaining weight and falling into disrepair.  One day I woke up and decided to take control over one aspect of my life that was out of balance: my own diet and exercise regimen.

So, that’s what I did. I lost 60 lbs.; got in better shape, started eating healthier, and now I want to share what I have learned with you.

With over 32 years of coaching athletes (i.e. Judo, wrestling and others) and general population from all ages (i.e. kids, young adults, adults, & elderly). I have the knowledge to tailor a program perfect for the busy professional.

The key to a better quality life is built through a positive mindset, consistency, discipline, and goal oriented exercise program that meets your individual goals, limitations/injuries, and lifestyle.

Let me help you achieve your goals, Whether it’s weight loss, building muscle, sports performance, or you just want to look good and get fit in general, 

Let me be the guide to unlock your potential and share what I’ve learned in my journey from a college wrestler to an overweight lawyer to fitness professional. 

Trust me, the journey won’t be easy, but it will be all worth it at the end. Book a session with me today, and let’s get your journey started.

I also teach Self-Defense and Mixed Martial Arts.  In addition over 20 years of wrestling, boxing and Muay Thai training, I have black belts in Judo and Kombatan (Filipino Martial Arts). And if you can’t swim, you really should learn. It’s a survival skill that I can teach you.

Training is only half the battle.  You’ve got to address your diet.  I am a Precision Nutrition Certified Coach.  I can guide you to eat healthier to complement your fitness program.

    A Word from Trainee

    "After three years of going seriously bonkers with my tech neck, keyboard elbows, computer shoulders, carpal and cubital stuff. Could hardly sit, stand or lie down. Name it, tried it: acupuncture, chiropractor, digital detox, ergonomic stuff, gadgets, osteopath, yoga, physiotherapy etc. Finally savior arrived in the form of Bill Mohler, the best Personal Trainer in the world. In four months at the gym we have gone from hardly being able to do anything to totally functional. Not once has it been boring, this kind and fun guy always comes up with new tricks and my muscles, nerves, joints love it. Today I am officially out of rehabilitation and moving on to building fitness! Halleluja!"

    "I have worked with Bill over the past four years. He is an extraordinary teacher and coach. In addition to his significant technical knowledge, he is a great listener and does a good job of tailoring workouts to your needs. He is also just a pleasure to spend time with."


    Gym Trainee

    "Training with Bill does it for me. I get bored in a gym easily. To stay in shape I'm used to changing things around in terms of how I exercise. With Bill I reached a new level. It's no longer about getting stronger, faster, more flexible, and agile. It's about getting full awareness and conscious control of my body for the life I want to enjoy. And, yeah, I get pretty strong and flexible in the process, which I, too, enjoy."


    Gym Trainee

    "Bill is among the most inspiring fitness professionals I have met. I have attended his yoga classes and his Yamuna ball rolling classes, and I have been relieved of severe back tension and pain through his thai massage. So, how is he inspiring? His style is not that of the "rahrah," over-muscled, steroidy body builder. Bill's style exudes strength and power that comes from his solid spiritual core. So whether he's guiding me through a yoga session, a Yamuna session, or even weight training, I feel growth, strength, and in healing in my spirit as well as my body. Bill's unique life experience and perspective makes this possible."
