"Jay is an amazing personal trainer. I’ve been getting all my goals achieved! He is an awesome person too and will educate you about all fitness exercises! I highly recommend him! Training with him was a great decision I made ! Thank you Jay"

"I started training with Jay in October but known him for a few years. Jay is very professional and listens to what my goals are and work with me to achieve it. He knows when and how to push my limits but also know when to back off when I'm having difficulty doing certain tasks due to minor restrictions. If you're looking for a personal trainer for whatever goals you're trying to achieve, I would highly recommend him."

"Jay is an absolute wizard of his craft. The improvement in my physique and overall strength have been immense. Jay provides detailed feedback and in set corrections that lead to increased gains and further understanding of how your body moves. He is also a great person to converse with during training so the sessions feel more personal and beneficial. I recommend JGRNZ fitness to anyone looking to truly improve on themselves"

"Jay is great! really pushes you to be the best and do your best. He worked though my sport injuries from high school. I have terrible knees that make doing some workouts hard. He worked though it and now my knees feel better and working out is a lot easier and reaching goals isn't painful"
