Personal Training

Are you ready to experience the Calibrate difference? Our team takes great pride in helping elite athletes and everyday folks take their performance to the next level. We are committed to helping our clients reach peak potential through an integrated approach to both athletic development and wellness alike. Unfortunately, when it comes to personal training today, there are far too many cookie-cutter programs. That’s not how we do things at Calibrate Sports in Littleton, though. Our personal trainers will always maximize client outcomes through a combination of comprehensive assessment, unique program design, treatment, training, and coaching. Our experienced trainers understand that in order for a client to achieve their goals, individualized care must be at the forefront of things. Rest assured that sessions will never be rushed and you can count on us to maintain a laser-focus on the details. Schedule your first personal training session with Calibrate Sports today.

Group Fitness

We offer a range of classes for all skill levels throughout the day. Calibrate Sports utilizes the latest technology and coaching techniques to create challenging and fun classes. In contrast to our personal training, group fitness is geared toward everyone working toward one goal. As opposed to local gyms where there can be a feeling of intimidation, Calibrate Sports is different. We welcome each client as a member of our team and family. By building relationships, our group fitness sessions turn into something much bigger. Team members encourage and push one another to extraordinary heights, making the sessions that much more effective.

About Our Trainers

The group fitness specialists and personal trainers at Calibrate Sports specialize in two areas: injury reconditioning and sports performance. Keep in mind that reconditioning focuses on the assessment, treatment, and development of athletes and active individuals with acute/chronic injuries and/or movement deficiencies. You can be comfortable knowing that our team will provide you with the tools, training, and treatment to help you look, feel, move, and perform at a level you never thought was possible, even after what seemed like a career-threatening setback.     

Our trainers value movement more than anything else in our coaching. We believe that fitness and reconditioning should be both fun and challenging. The staff at Calibrate Sports uses traditional methods while always being on the cutting edge of technology and science to customize your fitness program to address your specific needs. As aforementioned above, we never use a one-size-fits-all approach with clients. Though it may be convenient for us, it does our clients absolutely no good.  

Chris Nissler, the founder of Calibrate Sports, has built an impressive team of professionals who have made our fitness program the best in the area. We aren’t solely focused on personal training and group fitness, though. We are thrilled to have a number of strength coaches, manual therapists, and movement experts to implement a truly integrated strategy to health and wellness. The result is a one-of-a-kind model and environment in which folks of all ages and activity levels are able to thrive. Please don’t hesitate to ask about our personal training and group fitness sessions.
