“Our valuable clients deserve the best”

In October of 2015 I was debating on competing in my second NPC Championship. Even before I decided to do the show I knew for sure who I was going to call to be my prep coach and handle my diet and workouts. That would be Jamie Speiser at Precision Fitness and Spa. I t was a little over 3 years since my first competition and I have always followed Jamie on social media and it was apparent of the success he had with his clients. Every competition picture that got posted had him standing with his athlete with a medal around their neck! There are many things, but one thing that stuck out with Jamie is that he sincerely cares about his clients and wants them to succeed as bad as they want too themselves! In my 4 months of prep I went from 11.6% body fat to just under 4% and I gained several pounds of muscle in the process (And oh by the way, I was 48 years old for this competition and I took 1st place in my masters class!) If I were to do another show; he'd be my Go To coach, no doubt about it!!!

WOW !! GREAT !! TEAM WORK!!! POSITIVENESS !!!! SUPPORTIVE !!! ENCOURAGEMENT!!! YOU MEAN SOMETHING !!!!! WELL INFORMED!!! LIFE CHANGING !!!! These are just a few words that I experience working with Precision Fitness and SPA each day. Jamie Speiser and his staff are all of these and more and have kept me going through all the struggles and over the hills when the tough times have come. Before starting with Jamie I was the type of person that each day was from the chair to car to chair at work, back to car back to the couch. I was on oxygen at work and home, multiple medications my health and lifestyle was in a fast track to going to a fast end. My weight and condition was the "elephant in the room" that no one wanted to bring up to me as they didn't want to hurt me or my feelings. Then two people who changed my life and asked if I would meet someone that might be able to help me and they introduced me to Jamie Speiser. UNBELIEVABLE DAY FOR ME. HE OPENED THE WORLD BACK TO ME AND GAVE ME BACK MY LIFE. The simple things that people take for granted to be able to sit in a regular chair to watch your granddaughter dance. Be able to walk and play catch, go to the pool to go swimming, able to shovel your own snow and cut your own grass. All lift changing >>>>> I can go on forever about the numbers and the loss in lbs and inches ( which is awesome). The major changes I have experienced is the awareness I have gotten from Jamie and everyone at Precision Fitness and the courage and knowledge of making good healthy decisions at each meal. The challenging work-outs are tough but are adjusted to meet everyone's needs and abilities. They are fun and challenging the staff keep you wanting more and wanting to come back. Jamie Speiser , and the staff at Precision Fitness is a place that everyone can feel at ease. I hope everyone will come and try it for themselves.
