 It started as a different way to work out. I'm Army Staff Sergeant Alexander Henninger. I like to rock climb. When I'm putting on the gear to start the climb, I'm reliving every other time that I've gone climbing. It's like all those memories just come flooding back as I'm slipping my feet through the legs of the harness, tightening it down, putting the chalk bag on, tying the knots, making sure everything's done right. Check it, triple check it. It all comes rushing back and it's the best feeling ever. It's like a runner's high almost. When I look at the rock face and I'm getting ready to step up and start the climb, everything goes away. Any stress, any concerns that I have in the real world. Rock climbing to me in three words. Take. Challenging. Insane. And awesome.
