I work with Patrick because I trust his judgment and know he understands body mechanics, strength training, and sport specific fitness.  In addition to being a great skier and incredibly strong, Patrick is creative and passionate about fitness. His passion comes through every time I work out with him, which is very motivational.  All of these attributes more than make up for his thick French Canadian accent!"  -Jonny Moseley, Olympic Gold Medal Moguls, Nagano, 1998, X Games Silver Medalist

Michael KrickMichael Krick has been around the world. His passion for adventure has led him backpacking through Europe, skydiving in Argentina, swimming with sharks in Belize and surfing in Australia. This Arizona native has laid his roots in the Bay Area and discovered a way to unite his love of the outdoors, health and people: fitness.

His professional journey began at Saint Mary’s College where he earned his degree in Kinesiology. With a thirst for knowledge he then attained the notable CSCS certification. After managing fitness programs at a prestigious health club, he recognized his preference for working closely with individuals and helping them set, reach and maintain goals of health and wellness.

Michael Marizoni -  Michael is an experienced personal trainer with certification in TRX and  NASM Corrective Exercise.  Corrective exercise is the new buzzword in the fitness industry that the top fitness coaches and physical therapists are using to define a specific type of exercise selection. Corrective exercise is defined as movements that assist in creating balance, stability, and/or mobility in areas that are dysfunctional.Simply put, corrective exercise will be implemented into a program to assist an individual in cleaning up specific movement discrepancies. When you have a movement imbalance, you will be more susceptible to injury. I am going to go through certain issues I see in people and give corrective exercises that can assist each problem.

100%! Corrective exercise can not only help to reduce risk of injury but help you get more out of your workout,  game,  practice or hobby.  It can loosen up tight muscles, strengthen weak muscles as well as improve posture and coordination. You can apply corrective exercise workouts in short bursts as "movement preparation" before your main workout or use them as recovery days in between longer more intense workouts. Everyone should be performing corrective exercise techniques.


John SpongbergJohn Spongberg - 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 a nationally certified by the American College of Sports Medicine as a Health/Fitness Specialist as well as the National Strength and Conditioning Association.
