Who we are




LABoratory Kits



Handcrafted, Tailor-made Rehab unlike anything you have ever experienced. Whether you are rehabilitating after surgery, recovering from an injury, or dealing with the chronic stress of training, an athlete's body requires expert attention. Our therapists provide the most elite level of care throughout the continuum of your athletic career. 


This is where it all begins.  Discovery is the flagship kit of Four3 combining the full spectrum of our elite level testing equipment with Team Four3’s comprehensive physiological knowledge base. Leave nothing on the table.

What’s your dedication?  Four3 X Programming has been developed to set the standard of what personalized training should be in the endurance world.... NEVER STOP PUSHING


 Originally studied as a way to confer acclimation of heart rate, blood pressure, and exertion levels for athletes racing in higher temperature climates, research has found that heat stress training can improve performance in endurance athletes in their normal environments.  Four3 proudly embraces this research and has developed our Blue Heat program.


Through our research and work with endurance athletes Team Four3 has developed our Race Fueling Analysis (RFA). Nutrition and hydration can power you to your personal best… Don’t be left wondering if you are properly fueling.


Often seen as the gold standard for endurance performance testing, VO2 max measures the maximum amount of oxygen that can be utilized by the body during vigorous exercise. 


 Proper nutrition can mean the difference between a podium and a DNF. 


Team Four3 is proud to offer our athletes an elite level solution to gait analysis. Don’t leave your “analysis” up to someone with an iphone app.  



Proper joint mobility, soft tissue mobility, and motor patterns are directly linked with improved performance and decreased injury risk.  STAY AHEAD OF THE PACK!


 Determining your FTP is the cornerstone to setting up power and heart rate zones for cycling. We have found by combining MOXY testing at the same time as FTP testing the data points collected reflect much more of your complete athletic profile.




Feel you are missing something but not sure of exactly what you need? Our team’s expertise lies in consulting one on one with you to determine the specific tests, analysis, and tweaks you need to take your performance to the next level. Please contact us with your needs and we will develop a plan of attack and upfront pricing.
