Jay Morales
Hello I'm Jay Morales, a National Academy of Sports Medicine certified Personal Trainer and Corrective Exercise Specialist based in Miami, coaching clients in-person and online.
I specialize in helping clients lose weight, build strength and muscle, with a focus on growing legs and glutes for the women I train. I also teach practical self-defense, with a 15-year background in boxing and Muay Thai. I work with beginners, intermediate and advanced clients.
I got into coaching because I love helping people enhance their overall health. That's still what drives me to deliver the best training experience ever.

- Promise a specific amount of fat loss or muscle gain. Eating, sleep, stress and genetics all play a part.

What's the difference between a plan and custom coaching?
