About Jemaydi

Hi, my name is Jemaydi Mateo and exercise has changed my life. As a former collegiate baseball player, I have enjoyed training and competing since childhood. Despite my love for baseball, I would have never guessed that the game would help me through anxiety, depression and overall health. I think sports and exercise is one of the best tools to build a stronger body and help support better mental health. Now I have dedicated my life to personal training and helping people achieve their best body and mind. My priority is to make sure you achieve your goals in a safe, effective manner. Then making our sessions as enjoyable and engaging as possible. I enjoy working with athletes but, I have had experiences in helping clients transition after physical therapy, pre/ postnatal and weight loss. If you are excited to start training then I am the perfect match for you.

My favorite client story

My favorite client story will have to be this year I was training a lady that had back issues and since working with me she has no more back issues and lost 10 pounds.

My favorite exercise

My favorite exercise will have to be the squat because you have to be mentally ready to come up when you go down.

My favorite quote

My favorite quote will have to be from the movie
pursuit of happiness. “You got a dream... You gotta protect it. People can't do somethin' themselves, they wanna tell you you can't do it. If you want somethin', go get it. Period.”

My training experience

I been training baseball since I was 5 years old and throughout the years I learned from different coaches. When I finished college I decided to go to school for personal training and learn all I can.

It was my first time to train with trainer. I thought it is good to have a trainer to keep training without lazy cancellations! He customized each sessions for me depending on how much I am tired or enthusiastic, or hangover (he never had blamed me on this lol). Also he texts me to cheer up and advise about food often. Through 2 months ( 1-2 sessions per a week) training friendship likely, I lost 10 pounds and got slim shaped body. I went back to Japan for 3 weeks holiday, eating and sleeping almost everyday, it got me 5 pound back. However?!!)I again lost 5 pounds and got slimmed without training after coming back to NY! I found out that the training Jay customized me made my inner mustles very strong and lasting for long time. That is why I easily got slimmed. I do recommend him if you want to enjoy training with no pressures. I am sure that you will get healthy and strong body so soon!

I brought my fitness to the next level with Jay. He listened, customized a training plan, and we went to work, improving each sessions and incorporating new work outs! What gave me confidence in working with Jay was his attention to detail, helping me improve my technique, helping me to get the most out of each session safely! Jay has instilled so much confidence in me I felt like Rocky Balboa! Great trainer!

I enjoyed my training sessions with Jemaydi. He pays close attention to proper form and always challenges me to push myself. He has also helped me become more confident with incorporating weights into my workout routine. You can tell he is passionate about what he does and I appreciate his regular check ins and positive attitude.

Jeymadi is an exceptional trainer. He helped me correct my form on deadlifts and squats. Now I don’t have pain in my lower back. He’s very good at explaining and demonstrating technique. A genuine guy. I’d definitely recommend anyone to him.


I've been working with Jay for about four months. He is resourceful, energetic and thoughtful about his training sessions with me. He is dedicated to his craft and enthusiastic about coaching me to achieve my goals for my personal health. He encourages me to work harder and achieve more during each session. I enjoy our workouts very much.

Jemaydi is the man! I’ve been training with J for the past few months. When I started working with him, I had just come off a back injury that required physical therapy. J’s knowledge about the interconnecting muscle groups and their reliance upon one another to function allowed him to put together a workout plan that targeted the muscles that DIDNT hurt, in order to help the ones that did. After several weeks I’m feeling much better, I’ve gotten much stronger and have started to look athletic again. His “holistic” approach builds muscle without creating strain.
