What is Strength and Conditioning?
Before committing to a training partner, it is vital to understand the discipline. Strength and conditioning is a specialized field of sports science that uses exercise training to develop physical qualities such as muscular strength, power, endurance, speed, coordination, agility, and flexibility NSCA Basics. Unlike traditional bodybuilding, which often isolates muscles for aesthetic purposes, this approach focuses on improving overall athletic performance and reducing injury risk.
At Colfax Strong Strength and Conditioning, we define strength as the maximum force a muscle or muscle group can exert against resistance. We define conditioning as the ability of the body's energy systems to sustain physical effort over time. Together, these elements create a foundation for health that extends far beyond the gym walls.

Program Breakdown: Personal vs. Semi-Private
Choosing the right training format depends on your learning style, budget, and social preferences. We offer distinct pathways to ensure every member finds success.
