ABOUT US

Thank you for visiting Tucson Strength (formerly Evolution Fitness Systems). We are a training facility that offers Group Training and One on One Personal Training Programs. We specialize in helping people move better and becoming more conditioned.  Our team hold’s national personal training certifications and specialty certifications in kettlebell training, mobility, endurance training, rowing, and corrective exercise.

We view Personal Training not as the role of just a motivator (really anyone can be a cheerleader), but also as an educator, and as professionals in human movement. Many trainers now a days watch a YouTube Video of how to do a cool new workout and pass it on to clients without any understanding of how that workout will specifically effect that person.

Anyone can set up a workout that will make you sore, but exercise is more than just sweat and soreness. We have thoughtful programs that vary from One on One Training to Small Group Training, so whether your goal is weight loss, corrective exercise, high intensity training, or powerlifting we have program that will help you achieve your goals. Our Training philosophy is always based on making sure proper movement patterns are always used and then we focus to build intensity and strength on a healthy foundation.
