About Jonathan

Hello, I'm Jonathan Martinez Certified Personal Trainer in the Tampa, FL area. Growing up I wasn't the most fit child there could be I was the exact opposite. Due to this I encountered a host of health issues which is why I got into fitness. I have personally experienced the benefits of fitness and the power of nutrition. I'm here to help all my clients with their fitness/health goals. This is when i decided to become a Personal Trainer with one of the most respected names in the health/fitness industry the National Academy Of Sport Medicine. One of the only providers that are accredited by the National Commission for Certifying Agencies. I'm also a Certified Health Coach with the Dr. Sears Wellness Institute. My mission here is to have a positive impact on our client’s lives by creating a memorable fitness experience through advanced education, certification and specialized techniques, safe and effectively. I will deliver the best possible fitness and nutrition solutions to our clients needs through fun, challenging, appropriate and effective programs thereby being recognized as a unique and respected fitness resource for our community. This is more than just a job it is my PASSION.

My favorite client story

"I found Jonathan and it changed my life. I followed his instructions and lost over 70 pounds. I was able to start walking again without the help of a cane.

When I saw his video, I knew that this was the trainer that could help me get in shape and lose the weight that I had been struggling with for years. It took some work but Jonathan's workouts were tough enough to get me motivated and change my lifestyle."

My favorite exercise

My favorite exercise are definitely squats. Why? Simple, effective, and gets results.

My favorite quote

"You will never start until you take a leap of faith"

My training philosophy

Little by little. I don't just start the ground running the the hardest exercise of your life and expect you to stick with it. I plan everything from the group up for each and every individual. From our first session to our last. My nutrition philosophy is the same I make it work for you and around your life not the other way around.

My training experience

I've been training clients for over 4 years. Clients from all walks of life from college athletes, to people with disabilities, injuries, vets, medical professionals, and IT professionals. You name it I've more than likely worked with them. I understand the struggle that all of my clients go through because I personally have been through hardships as well.

I worked with Jonathan for over three months doing cardio and strength exercises. I was 138 lbs and now I am 124 pounds. He also help me to learn about nutrition and how to eat correctly. I am very excited of the changes I have accomplished in my life working with Jonathan. I recommend him to anyone who wants to have a one on one exercise and nutrition training.

Jonathan has been a great help in my quest for healthier and fit lifestyle. His recommendations on nutrition and healthy habits have made the workouts better from the get go. I’ve already started to lose weight and beginning to feel the workouts paying off.

Commonly the first thought of a personal trainer would be the expenses and no time after work. I used to weigh over 175 pounds, and in less than three months I have lost 15 pounds. Jonathan stands by what his knowledge is all about which is nutrition, diet and corrective forms. He thinks/talks about realistic goals, and thats why I endorse my highest recommendation to him.

He understands training and exercise techniques

Jonathan has helped me lose weight in a fun and easy way. We started 3 weeks ago and I've lost 9 pounds so far I am so excited and happy to continue training with Jonathan! ????? 5 stars I highly recommend him.


Amazing Ethic and Personality. Jonathan is friendly, knowledgeable and encouraging. His creativity makes exercising enjoyable. This is coming from someone who does not like to exercise at all. I have learned a great deal from Jonathan and cannot thank him enough for the progress I have made towards my fitness and life-changing goals.
