On Thursday, Beckham completed his daily round of 22 push-ups on top of a piano inside his Las Vegas hotel room while wearing nothing but his underwear.

"It's for a great cause, a serious cause, for all the service men and woman that take their lives every single day," the father of four says after completing his push-ups (without knocking over a bottle of wine and two glasses sitting on the piano).

Beckham then pans the camera to show off his hotel room. "I'm 79 floors up, I’m lying on a piano and I thought I’d bring a pianist with me. I thought you’d find it romantic," he jokes.

Each day appears to be a special location for Beckham. He started off the "first lot" of push-ups from 44,000 feet in the air. In his most recent video, Beckham finishes the push-ups in his hotel room, only this time he's fully clothed.

"Day 3 of the#22pushupchallenge to raise awareness of the devastating effects of PTSD on the lives of servicemen, servicewoman & their families," he captioned the third Instagram video. "I won't be posting these everyday so as not to clutter your feed but trust that I will be doing them and you will see the evidence. This cause is too important to me."
