Rey Mysterio Jr. is without a doubt one of the greatest high-flyers in the history of professional wrestling.
At a billed height of just 5'6" - possibly shorter - Mysterio Jr. made a name for himself in the giant's world of wrestling through an innovative offense that many audiences outside of Mexico hadn't seen before.
It's what commonly known as the 'Lucha Libre' style, but through his time in WCW and then his 13 years with the WWE, Mysterio was a pioneer of the craft and helped influence a whole new generation of acrobatic wrestlers today, embodied by independent stars like Riccochet and Will Ospreay.

Ultimately, Mysterio had to leave the hard grind of the WWE as his injuries and troublesome knees started to get on top of him.
However, at 41-years-old (he seems like he should be older, doesn't he?), Mysterio Jr. is showing it is never too late to get yourself in shape.
In a recent Instagram post, the former three-time world champion in WWE posted a photo of himself looking more muscular than ever. In the caption, the San Diego-native gives his reasoning for the bodybuilding stating: "My main goal is to push & motivate my son cuz I know he will turn into a complete BEAST!"
Mysterio Jr. has also just signed a one-year first look deal with El Rey, the network behind the Lucha Underground series in which he currently appears.
Under the agreement, the veteran will develop, produce and consult on creative projects and series, both scripted and unscripted.
It doesn't appear as though Mysterio Jr. is going anywhere anytime soon, but wherever he does surface next, he sure is going to look jacked.
