Thirty-two athletes piled into the WWE Performance Center today to begin tryouts for a contract and this video the company released gives some cool insight into how it all goes down.

According to WWE.com ... the tryout takes place over the next 3 days and features athletes with backgrounds spanning the NFL, NCAA wrestling, mixed martial arts and other sports.

In the video below, the large group of hopefuls are mainly practicing rolls -- but it's interesting to hear head coach Matt Bloom critique each individual while people like Gerald Brisco, Sara Amato, William Regal and Triple H watch with a keen eye.

NXT tag team The Revival are also seen helping the potential talent outside of the ring ... as well as Alexa Bliss, Tough Enough contestant Daria Berenato and NXT referee Danilo Anfibio.
