Capacity vs Capability

Core Difference
Capacity reflects what an athlete can do in isolation, while capability reflects what they can do under realistic conditions.

Capacity Focus
Capacity is measured through tests such as maximal strength, VO₂max, or time trials.

Capability Focus
Capability reflects task execution under fatigue, stress, load, and environmental constraints.

Why the Difference Matters
High capacity does not guarantee usable performance in operational or unpredictable settings.

Key Takeaway
Training must convert capacity into capability through context-relevant exposure.

What Is Training Load? | What Is Fatigue? | What Is Recovery?

Combat Fitness exists to produce capable humans. Tactical fitness for military, law enforcement, and people who refuse to be weak. We focus on strength, work capacity, endurance, and resilience that transfer outside the gym. No trends. No feel-good bullshit. Just hard training for people who expect more from themselves.
