Client experience:


I’ve been training with Dan for about five years now. He is the man when it comes to keeping you physically fit and healthy. I originally started to see him to work on lower back pains and a knee pain due to old injuries. He cured them! Since then he has helped me work out every physical ailment and injury that I’ve gotten. I’m pretty physically active and enjoy the extreme end of sports and Dan keeps me together! Dan has a dynamic approach to body mechanics, coming through with diverse disciplines and techniques. Before working with him, I would have to get massages, Acupuncture and go to the chiropractor regularly. Not anymore, maybe only once or twice a year now to just to stay in tune. Always bringing on new challenges for me after all these years, he is the best!

He gets to know you, understanding your weak areas and any injuries, and adjusts to ensure that you work those muscles without the risk of re-injury. Pete's passion for fitness and people is what makes him so good at what he does.

He exudes confidence and gets you to believe in yourself, and you get to a point where you don't want to let him down, so you push yourself to complete that next set or next few reps. As a consummate professional he is always learning, this is demonstrated by his follow through in that after a hard workout he checks in to see how you are doing, so that he understands the recovery process, and plans for the next workout.

I would recommend working out with Pete to anyone who is tired of the same routine and is interested in real results.

Moda 3000

Dan is truly one of a kind and the absolute best at what he does. His knowledge, professionalism, and passion for fitness are unmatched.

One of the things that sets him apart is his holistic approach to biomechanics. He not only focus on improving movement patterns but also address underlying imbalances, weaknesses, and lifestyle factors that contribute to long-term health and performance.

He has a unique ability to push you beyond your limits while keeping the sessions fun and engaging. His attention to form and detail ensures you’re always doing exercises safely and effectively.

He has genuine care for his clients. Dan’s not just a trainer – he’s a mentor and a cheerleader, always encouraging you to be your best self inside and outside the gym.

Training at Kayser Fitness has changed my life. I used to think that because I surfed frequently I was in shape, but my back hurt all the time. Those days are long gone, I surf more than ever and at a higher level without any body pain. My quality of life has improved so much. Dan has an amazing ability to read the human body to prevent and remedy issues as they arise. 100% recommend Dan to all my friends.

My Knee Hurts When I Squat, Can I Still Workout Or Should I Get It Fixed It First?

 At Kayser Fitness Institute, the first thing we will do is screen you for all muscular and structural imbalances in order to address any underlying issues and pains you might be experiencing.  We will help you fix all your issues, including those you may not be aware of.  When you lift weights with imbalances and asymmetries you will only strengthen those dysfunctions.  Let us help clean up your vessel, build a solid foundation and top it off with proper strength.
