I have been using Jason as my Personal Trainer since March, 2011. At first, I was very skeptical, but after my first few sessions, I was impressed with his professionalism and knowledge and decided to make a commitment. I have worked out for many years on my own without success in changing my body. At 5'2", I only lost about 15 pounds but they came off very quickly. During this time, he has taught me that through weight training, my body would change and it did change. I went from wearing a size 10 to a size 4 because of weight training with him. One of the first topics we talked about was food. He taught me that I need to eat in order to change my body. I currently eat 6 times a day and enjoy every morsel since I love to cook and eat. As a current client, he continues to challenge my body and helps work through any injuries or illnesses I have endured. Jason listened to my goals and continues to develop a plan that is challenging, fun and effective. His online program is creative, and keeps me motivated. I am always excited to receive the next weeks plan. He makes it very easy to communicate through email, texting or by phone. I highly recommend Jason as a Personal Trainer if you want to succeed in establishing your fitness goals, working hard towards those goals and enjoying the benefits of a healthy, strong body.

In education there is a difference between a foundational understanding and a deeply rooted passion for mastery; one leads to adequacy and the other excellence. Jason is the latter. ?Instead of implementing a preconceived plan modified to fit the client, Jason takes the time to gauge and listen to the client and their body, inventing a plan ideal for that individual and their unique goals. He continues as partnership constantly refining and redefining the plan based on the client and their body's response. Pulling from his incredibly vast knowledge base inherent only to someone who retains a deep passion for his craft combined with instinctive care for the client's goals, generates the perfect recipe for success and achievement.

Jason is an excellent personal trainer. I was lucky enough to work out with Jason twice a week for over 2 years. He has an easy-going, friendly personality that quickly creates a comfortable atmosphere. He helps you articulate your goals and tailors programs specifically for you. He is non-judgmental regarding where you are on the fitness scale. He is thoughtful, encouraging and always professional. Every workout is different and designed with you in mind. Jason maintains an expertise in the latest fitness knowledge, and nutrition information. I recommend him without reservation.

Jason is an amazing trainer. He truly cares about his clients and he takes a holistic approach toward training. He guides his clients with advice on proper nutrition and emotional well being.

"I trained with Jason for the better part of 6 months and in that time could not have been happier with the results. He is a great trainer not only because he achieves great results with his clients, but he has an incredible wealth of knowledge when it comes to health itself. Whether it be advice on what to eat, or the best exercises for a quick workout when you're on the go, Jason covers the full spectrum in a fun, engaging and results-oriented way."

I had worked with other personal trainers, but I never experienced the same level of dedication and professionalism as I did working with Jason. As a trainer during sessions and as a supporter when we were not in session, Jason and I worked as a team focused on achieving my goals. I have health concerns such as chronic pain and fatigue. Jason was great at customizing plans that worked with my limitations, and we significantly improved my strength and endurance. Most important to me, Jason made it fun by varying the workouts, and motivational by celebrating the accomplishments. I may not have wanted to do the last squat at the end of a series, but he always helped me find a way to do just one more. And that made me feel strong.

"I started seeing Jason when I came to the point of not knowing how to workout on my own. I would walk into the gym, get on the treadmill, and leave. I knew I needed more of a challenge and wanted more out of my workout routine. Jason changed all of this for me. He is well educated and when it comes to health and fitness, his passion is incredible. From day one Jason helped guide me and educate me on all different types of fitness, and even challenged my ability mentally. Jason truly cares about your personal well-being and is very supportive and motivating. Jason was not just a coach in the gym, he was a coach outside where he was always available for nutrition input and what types of workouts to complete on my own when I was not working with him. Jason is amazing and after seeing him I felt healthier than ever!"

"Jason is amazing!!! He helped me lose close to 20 pounds and is very personable and reliable. I wish he lived in Colorado still because I would definitely still be training with him. He is well educated when it comes to training as well as making great recommendations for nutrition."

Jason is a great trainer. I had the pleasure of training with Jason in 2010. He is professional, knowledgeable, and motivational. He took me back 20 years through strength training, cardio, and nutrition. We successfully reduced body fat and increased muscle mass, strength, and endurance. Importantly, Jason was instructional which allowed me to take and apply his expertise, knowledge, and program on the road for business. I recommend Jason to anyone looking for an accomplished personal trainer and anyone looking for real results.

I had the pleasure of training with Jason for 2 years in Colorado. He is an excellent trainer and is dialed-in and 100% focused every day on his clients. He listened to my concerns and always kept my overall fitness goals in mind. His upbeat, positive attitude can get you through even the toughest workouts. I would highly recommend him to anyone looking for a trainer who is extremely knowledgeable in both fitness and nutrition, and always has his clients best interests at the forefront of every workout. Truly a trainer with heart.

Let me begin by telling you that Jason is an awesome personal trainer. He really epitomizes the world "personal" because without being evasive he gets to know you from the perspective of health, and he never makes you feel ashamed of your present condition, your results or lack thereof and yet you get a full understanding of yourself and what it is going to take to be a more healthy you. Jason and I have been working together now for almost a year, give or take, and I have to say, the results have been tremendous. I am constantly getting compliments about the changes in my body, so much so that it starts to make me wonder if I was delusional about how I looked prior to meeting Jason. I'm getting into clothes that I haven't been able to wear in over two years, and no I don't care if they are out of style, my booty can fit in them again and that's all that matters to me... (LOL). There's a lot I can say about Jason and his abilities as a trainer, but I'm not going to take up all of his space. But I will tell you this he walks the talk yet he never makes you feel less than because you are just learning. He recognizes it takes time and that time is different for everyone. He sincerely cares about your success. He is constantly encouraging you, and pulling for you, all without overwhelming you or being annoying. Furthermore, Jason realizes and stresses that we need to listen to our bodies, but hear me when I say this, he knows the difference between listening to your body and flaking out... Jason is all about being smart about getting healthy; he's never going to push you beyond your limit but he is going to push you to reach your limit and there is a difference. I guarantee you if you listen to Jason, you won't be dissatisfied or regretful. ?Now if this has not convinced you that Jason is the PT for you, I dare you to give him one hour of your time, and I'm willing to bet that you will walk away wanting more.

My training with Jason was the first time I had ever used a personal fitness trainer. He listened, encouraged, always provided feedback and I saw results.

Sheree C.

Jason is extremely knowledgeable about all aspects of fitness and very professional. He helped me reach my goals by making a plan with consistent expectations and accountability. With his nutrition plan and workouts, I achieved my goal in just a few months. I highly recommend Jason. You will not be disappointed!

Laura G.

Jason is personable, prepared and disciplined in executing workout plans. He quickly learned my workout level and pressure points, made every single workout highly efficient and effective. He worked on my form regularly, make sure when I work out on my own, I get the best results. I walked away from each workout feeling great, and Jason would motivate me to stay on a regular workout routine, outside of our sessions. Lastly, he is just a nice guy.” - Lisa O. (Los Angeles, CA)

Jason Williams is one of the most dedicated and driven people I have ever met. His attention to detail, his knowledge of his profession, and his high character are just a few of the things that make him great. I would recommend him to anybody.
