Sheamus trained with US Marine Brandon Rumbaugh, who is a double amputee, in this new video from his Celtic Warrior Workouts YouTube channel.. 

The description of the video reads

WWE Superstar Sheamus aka The Celtic Warrior here... It's not many times in life when I am completely blown-away by and individual. The first time I met Brandon Rumbaugh, I was totally blown-away. Not only has this US Marine VET come back from losing both legs to an IED, he's now standing even taller than before and kills-it in the gym 5 days a week plus inspires people all over the world with his never-lay-down story.

If there even was a human being that embodies the Brave Change it's Brandon Rumbaugh. If you think you have excuses not to hit the gym, get healthy and achieve your goals in life, watch this video and... Brave Change.

He also posted the workout he did with him.
