10 Stars Who Got Ripped After They Left WWE

10. Rey Mysterio

Using his diminutive frame and lightening fast reactions to get the better of his foes throughout his stellar career, Rey Mysterio appeared to be content with his slight frame and had definitely earned his fair share of success with the body he had.

Yet, when the masked sensation finally left WWE in 2015 he clearly felt that it was time for a change.

Replacing the cardio with free weights and a new diet plan, Mysterio posted a picture on his Instagram in August 2016 which outlined just how insanely hench the 'Master of the 619' had become in the time since leaving Vince McMahon's company behind.

Mysterio legitimately looked like an absolute tank and it took a while for some fans to adjust to the image of the once plucky little man now looking like he could crush a watermelon just by giving it a loving hug.

When Mysterio finally did return to WWE shores in 2018, the luchador looked like a star reborn and his improved fitness appeared to have given him a new lease on life. Incredibly, this newly shredded version of Mysterio began to churn out bangers on par with his early 2000 work and his new found focus on nutrition seems to have provided him with a few more years at the highest level.
