A photo snapped by a Planet Fitness employee in Tennessee has quickly gone viral on Facebook, and with good reason. 

Lezlie Bauler said a man walked into her gym and asked if he could climb 110 sets of stairs, fully suited, in honor of his fallen brothers and sisters of 9/11.

Bauler wrote, "I am not one to get emotional, but a few tears were shed. Thank you for your services." 

That post has received more than 60,000 shares. 

The firefighter in the viral photo, Jason Harding, released this statement:

"When I went to the gym this morning at 6am before coming onto shift I was only wanting to honor the fallen heroes and their families on this day 15 years ago. I was not and am still not looking for any self recognition. I have received so may private messages via Facebook from people expressing that support, gratitude and blessings. Many stated my act brought them to tears but little do they know, their support did the same for me. I want to thank everyone that shared and commented in response to this post. It it proof that although we seem divided as a country at times, we unite at the most crucial times. As a Public Safety Officer and McGhee Tyson airport officer, I am honored to be a Firefighter, a Police Officer and a Paramedic. I have been in emergency services for the most of my career after college and wouldn't change that for anything. There are memorial stair climbs all across the country today honoring just as I did. I have participated in Nashville's Memorial Stair Climb for the past 4 years. Unable to make it this year I decided to honor anyway."
