Life Video

 A pair of dedicated firefighters took to gym stairmasters to climb 110 floors while dressed in their full gear in memory of September 11 victims.

 Decked out in their uniforms, helmets and with one even carrying an oxygen tank, the everyday heroes take step after step in a Planet Fitness in Bonaire, Georgia.

 The duo began their ascent at 8.46am on Tuesday, the moment American Airlines Flight 11 hit the north tower.

In less than 24 hours, the video has had more than 17 million views.
