"Chris Grayson is one of the most knowledgable coaches that I have ever worked with. I have a pretty solid background in fitness and have worked with a lot of different coaches over the years, but without a doubt Chris is the best."

“World Class Strength and Conditioning coach. Chicago’s best kept secret. If you want to get in the best shape of your life, contact Chris Grayson. By far the best I have trained with.”
“I’ve been training with chris off and on for years. The greatest thing about the Urban Strength Institute is that Chris takes all the “guess work” out of it. If you show up and give your best effort, you WILL achieve your desired results. I’ve worked with Chris for fat loss, endurance training, and strength training and […]
"I have been consulting and training with Chris Grayson for nearly a decade. He has always delivered solid training advice. I know of no other trainer today that puts as much time into reading and developing the craft of training as he does."
"Chris is a continual learner, and has a wealth of knowledge. When you train with Chis, you're not only a trainee, but you're a student. Chris really wants to impart knowledge to those he trains, but it's also obvious that he wants to listen to you too."
I’ve been training with with Chris for a little over a year now, and it’s a testament to his skill that I’m still at it. Like many people, I’ve struggled staying consistent with training, usually doing well for about 6 months before starting to slack off due to a combination of life’s stresses and hitting […]
As a 6 year Brazilian Jiu-jitsu practitioner and competitor I can honestly say that I've never felt more prepared and at my physical peak for BJJ competitions than I have training at USI under Chris Grayson.
For me, it's the first time I've ever seen results from training ever. To date, I'm up 10 pounds, and have received compliments from friends and family who have noticed physical changes in my body. My arms and legs are bigger and more toned, and almost weekly during training, I notice that I'm able to lift more weight.
I came to Chris in July of 2016 with some very specific strength and performance based goals that I had finally committed to accomplishing; since I am in the field of Strength and Conditioning and bodywork I was in search of an expert. After doing extensive research on some of the best personal trainers in […]
I have been training with Chris Grayson for nearly a year now and here are the main reasons I believe USI is an absolute gem: - Chris truly cares about your performance. Your progress is his top priority so he will not hesitate to talk to you honestly even if you don't like it. - He is very knowledgeable.
I can honestly say that Chris Grayson is at the top of his field. I am always impressed by his extensive knowledge, no nonsense approach, and ways in which he challenges himself as a professional to continually learn and improve.
I have been training with Chris for about two years now and have received compliments from friends and colleagues about how my body is much more defined and trimmer since I started working out with him. Not only can I lift more weight, my cardio has improved greatly as well, and my nutrition and eating habits have changed because of his guidance. I can't recommend Chris and the USI enough- this IS the best-kept secret in Chicago.
"I followed his advice and in only 4-5 months the results are undeniable: I am unrecognizable in pictures (in a good way) having gained 30lbs of muscle; I am objectively much stronger (Chris writes down every session so you can see and compare your own progress); and I went from doing 0 to 4+ consecutive pull-ups, which was a BIG goal of mine."
