The Chester Step Test is a standardised method of assessing the aerobic fitness of firefighters.
It is based on the timed walking of a set distance, up and down a set of steps of varying heights.
The test is designed to simulate the conditions that firefighters would face in an emergency situation, and so it is an important tool for gauging their readiness for duty.
The Chester Step Test is a demanding physical challenge, but it is an essential part of ensuring that firefighters are fit and able to meet the demands of their job.
