There are many inspiring sports videos on this site, but you really need to watch this woman. Former gymnast Kacy Catanzaro doing her thing in TV show American Ninja Warrior will make your shoulders ache. Ok, very cheesy show-name but just wait till she gets onto the rings - incredible upper-body strength.
Enjoy! (and be warned you will want to get off-line right away!)
