James is a passionate, committed, and dedicated personal trainer. His worth ethic is inspiring and second to none. My mom and I worked with James to build healthy habits and transform our pandemic sedentary lifestyle. Now, after working with James for many months, I feel the strongest I have ever been. James holistic approach focuses on the whole picture of health, not just the image of a fit body. James coached me through strength training, cardio, and nutrition. James is an active listener who would assist and tailor my goals. I learned about ways to stay loyal to myself and my goals through our weekly coach chats on the phone with James. It was never about being perfect but about building a healthy daily lifestyle routine. James gratitude practice has made me slow down and reflect more on what I am grateful for in life. I am grateful for James, and all that he taught me. James as a coach was consistent, flexible, and always encouraging. Additionally, James is engaging and funny. He made the sessions fun and enjoyable. 10/10 would recommend James King III!

I have tried connecting another health, wellness and life coaches before and none of it ever stuck until James. He is an absolute master of his craft, he will be your biggest fan, your number one supporter, and make your success in learning lifelong habits his own personal goal. I truly dont know where he finds the time and space to authentically connect with all his clients but I genuinely look forward to all my virtual calls with James. He listens, and adapted a workout schedule, diet and health practices to my busy schedule and wanting to be able to do everything from home without a gym membership. To anyone even considering a coach I can say with 100% certainty to look no further. There has not been a better investment that I have made into my own personal physical and mental health then my time spent learning and being coached by James.

Thanks, Julien! Coaching you has truly been a pleasure! Seeing the progress you’ve made, habit-wise and physically, over the past year and a half is really special. Look forward to seeing you enter this next chapter. Cardio mode, here we come! Happy to be in your corner

Ive worked with James twice weekly for over 8 years, and I can safely say its one of the best decisions and investments I have made. Ive lost and maintained a healthy weight, trained for and participated in runs and other sporting events, and grown noticeably stronger during our time together, but what really sets James apart are his attitude and approach. He is motivating and helpful, and never judgmental or intimidating. Process, form, purpose, and incremental success are all prioritized over immediate gratification, and he is excellent at making in-workout adjustments to maximize our time together. James really listens to me when setting out a plan to achieve my fitness goals, and he takes my mental and emotional health just as seriously as my physical health. Gratitude questions at the end of our workouts keep me focused and appreciative of the little things, and accountability check-ins make sure Im staying on track. Whether I miss a workout or Im stacking my wins, his questions always center around the why - what worked, what didnt work, and what adjustments need to be made.James is not only an excellent personal trainer, hes an excellent human, and I cant recommend him enough.

Working with James was one of the best decisions my wife, Brittany, and I have ever made. We originally started training with James to prepare for our wedding, but it quickly became clear that his impact went well beyond that. We specifically sought out James because of his positive attitude, sense of humor, and his holistic approach to fitness. He brings deep expertise not only in strength training, but also in nutrition, sleep, and sustainable lifestyle changes.Now, more than two years later, we genuinely couldnt imagine our lives without him. My wife and I have different fitness goals, and James has been incredible at tailoring our programs individually while still making training something we enjoy doing together. He keeps us accountable, celebrates our progress, and supports us through every step of the journey.On top of being a phenomenal trainer, James has become a trusted friend. If youre looking for someone who is knowledgeable, motivating, and truly invested in your well-being, we cant recommend him enough.

One of my closest friends mentioned he had started working with a personal trainer named James King. At that time I was slightly overweight and not in great physical condition. I decided to give this "personal training" idea a shot. I contacted James and began what has now been one of the best decisions I have ever made. My biggest concern when I started this journey was that I would have to follow some rigid ideology which would be an impossible task for me. I was over 50 years old at that time and as anyone that age had developed certain habits that would be very difficult to change. All of my worries would soon disappear and I found myself making positive strides in regards to my health without the rigidity I feared. James understanding of what it means to be healthy is all encompassing. I did not have to become a different person. I did not have to stop doing the things that gave me joy. I did not have to be militant about my dietary habits. I just had to understand that by making several small changes in my life, I could achieve amazing results that made me look better, feel better and be better. I started as a 215 pound man that could barely do one pull-up and have turned into a 175 pound healthy, energetic, and happy man able to do a few sets of 10 to 12 pull-ups at one time.If you are interested in becoming a better, healthier, and happier version of yourself, I would highly recommend hiring James to help you, motivate you, and transform you into the best version of who you already are at your core.James is truly a king and I am truly honored to have met him and call him my friend.Leonardo Umansky
