Spencer pushes me every workout I can surely say that after every workout I am excited to come back for the next one. Not only has he provided expert advice on what to do and what not to do but he delivers it in a respectful manner. He loves joking around which helps the sessions go by so no matter what I am always having fun!

Spencer has been training me since Sept of 2020 and in this time he has helped me achieve the goals that we both set.  Not only has he helped with my fitness goals, I look forward to my workouts as Spencer makes them fun, different and challenging.  On top of all this, Spencer is super personable and helps the workouts fly by by keeping me engaged.  And lastly, I have worked out with trainers in the past but what sets Spencer apart is that he always watches my form and provides constructive feedback after each exercise.  Thanks for all your amazing support and guidance Spencer and I look forward to you helping me achieve my fitness goals in 2021.

Spencer was very professional and helped explain all work outs he sought fit. He helped me improve my form on most if not all exercises and he helped me focus and achieve my goals. Spencer is someone that wants you to achieve your best and I would have not changed anything while working with him

When I retired and after years of sitting behind a desk I decided I needed to get into shape. The goal was to lose excess weight while not getting injured. Spencer was able to take me from zero to where I was very comfortable in the gym with all the equipment and using them correctly.
He also created workout routines that were updated on a regular basis. These routines were fun and kept me interested in training. He also introduced me to an online training app. This tracked my progress and allowed me to train without having to think about what I was doing. Spencer is very dedicated to providing fun and challenging workouts that provide steady results while keeping your body injury free. I was extremely satisfied with his training program and would have no issues with recommending him to anyone.
