If you're looking for a gym that feels like a family, this is the place. If you want an informed approach to training, this is the place. If you want to see real progress...you get the point.
I've seen some significant strength gains and learned a lot about effective training in a few short months here. The coaches are awesome, as are the other members.

My Son has been coming to Diesel for a year now and we absolutely love Ali, Greg, and their Family! We came in to make sure my son was getting what he needed strength training wise for his baseball, and he absolutely fell in love with it all! He now competes in weightlifting for his off season sport with Team Diesel and we couldn't be happier with his training! The members are great as well! Thanks Ali and Greg! #doyoudiesel

I don’t think it’s possible for me to say enough good things about Ali and Greg and their entire family. I have been training with them since about 2013 and had absolutely zero experience in the gym when I first started.

They focus on the fundamentals before ever recommending any weights. They also have vast medical knowledge to explain why you’re doing something rather than just telling you to train a certain way. They’ll listen to your individual goals and help map out a plan of attack.

From stretching to strength training as well as nutrition, Diesel is about expanding the capabilities of ourselves both mentally and physically. Not only has my physique improved since joining their gym but I live an overall healthier lifestyle thanks to their coaching.

Diesel also operates as a non-profit, providing training to under privileged athletes across N Florida.

Again, words cannot convey the immense pleasure I have had working w the entire Cosentino family.

I have been apart of diesel on and off for over 6 yrs. I trust this gym with compared to many other local places I have checked out. Not only do they provide programming that is safe, they consider injuries. I have used them pre and post with multiple pregnancies. This gym is small and personal. They can help you reach your personal goals realistically and safely. I really wouldn't go anywhere else.

I’ve made so much progress! While I’ve been interested in fitness/ working out for years, I’ve never seen these sort of results. I’m getting stronger every single week, and I get to workout with a great group of people.

I was in town for a day and contacted Ali about dropping in for a single powerlifting workout. She was responsive and kind. Initially, I felt like a fish out of water. Working out at a new gym is always an experience. I had so many questions. How heavy is this bar? Where do you keep the collars? Where do you keep a dip belt? Everyone was so helpful and kind. Thank you!

This is the first crossfit gym that I've ever been to that I was genuinely sad when I had to transfer out of the area. Coaches Ali and Greg are really great people who actually care about their people and their progress. Everyone I met here was super friendly and positive and it's such a great environment to be surrounded by. Definitely gonna miss Ali and Greg and will recommend this gym to anyone I know that's in the Jacksonville area.

Awesome coaches and a supportive environment. Ali and Greg have helped me set goals and achieve them. I wouldn't work out anywhere else!

I cannot speak highly enough of this gym. With so many to choose from, my decision to join came down to ownership. This husband and wife team has devoted their entire adult life to health and fitness and, most importantly, share their breadth and depth of knowledge in a way that achieves results. My son and I have attended for over four years now and remain injury free and in the best shape of our lives. My son has now moved off to college with a foundation of strength and fitness that will enable him to pursue his current goal of military service in the special forces community. Bottom line, there are many gyms to choose from but none with coaches that have comparable resumes.

Moving to Florida, I was worried I wouldn't find a gym where I could do power lifting and Olympic lifting and also get some conditioning sessions in. I was also looking for a "team"'aspect environment. Well I found it at Diesel. Greg and Ali have coached me better than the stength and conditioning coaches I had at Penn state and not mentioned have also helped me cut 5% body fat! Also the people I work out with are the reason I go everyday at 6 am!

Greg and Ali are awesome. After working out at other boxes, none compare to the expertise of Greg and Ali. They push you to achieve your best and the programs are intense. Can't wait to one day move back to Jax and call this box home again.
