A photo of a firefighter working out in his gear has gone viral after he was seen working out on 9/11.

The firefighter, who is from Tennessee, elected to wear all of his gear while on the Stairmaster in honor of those who you died while serving on 9/11.

While in a Planet Fitness gym, Jason Harding decided to use the machine to climb 110 flights of stairs. That's how many flights of stairs some firefighters had to climb in the World Trade Center towers 15-years ago to reach people.

Sadly, many of those who climbed the stairs on that day never got of the buildings.

What a gesture by this young man and what a way to honor his fellow firefighters. We salute you and all of those who risk their life to protect us.
