     Trustindex verifies that the original source of the review is Google. I simply cannot recommend Diaz Fit enough. I’m a student at the U of A who trained with both Jaime and David in group sessions over the course of 4 months. All the trainers are highly knowledgable, dedicated, personable, and encouraging during every visit. If you’re intimidated by the dynamics of larger gyms and are looking for a place where people are approachable; are interested in learning correct technique; and/or are looking for a place to make strides at whatever stage you find yourself, this is that place. 10/10

     Trustindex verifies that the original source of the review is Google. I am a 71-year-old retired professional woman. I joined Diazfit in July 2023. After an initial one hour consultation with Jaime Diaz I took a few days to consider my options. There is no on-site pressure to sign up or any contracts. Since joining, I’ve worked with 2 different trainers. Each one is excellent because Jaime is very particular about his employees. In addition to getting personalised training, I have a personalised nutrition program. There is no standard food or exercise routine at Diazfit like in other gyms. And, I lost over 60 lbs, dropped my A1C to normal, and have increased energy. I have worked out my entire adult life, and this gym is the best ever. It is small yet complete and scrupulously clean. There is no waiting for machines or trying to plough through hordes of people posturing and flirting. Diazfit is a diverse community of friendly people with the common goal of lifetime fitness. I’d venture to say we are almost a little family. Come join us!

     Trustindex verifies that the original source of the review is Google. My husband and I have been going to Diaz Fit for 2 years now. We started with personal training which was instrumental in getting started on my strength and mobility after having a 35yr desk career.  I am now 30 lbs lighter and better shape than I had been for 20 years.  We now use the gym for the equipment and space. It is nice to have a private gym that is safe and not overcrowded.

     Trustindex verifies that the original source of the review is Google. After trying several gyms, nutritionists, and hormone specialist with no success. I was referred to Jaime at Diaz Fitness. Jaime provided me with a nutrition program and a personalized workout program that has allowed me to reach my personal weight and health goals. If you are looking for a life style change to improve your health and fitness, schedule an appointment. It will be one of the best decisions you will ever make. Carmen Whetstone

     Trustindex verifies that the original source of the review is Google. Jaime has been a positive force in my health journey. In only three months, through diet and exercise, I have seen a major improvement in my body composition. A noticeable increase in strength and muscle mass. Targeted stretches and exercises helped rid my shoulder of rotator cuff pain, which was probably caused by underdeveloped muscle. I was signed up for Jaime's semi-private personal training program and it was the perfect choice for me. Just the right amount of personal instruction with added benefit of diet/nutritional help for optimal results. My health is on the right track with what I've learned from Jaime.

     Trustindex verifies that the original source of the review is Google. Best place to train. Super knowledgeable owner- he listens to where you are at and where you want to be. Gives reasonable goals to meet or challenges you to go harder. You let him know your wants, and he will get you there. Nice atmosphere, comfortable and clean. Recommended!
