Rick Ross wants to brush up his fighting skills -- so, he strapped on the gloves and hit the boxing gym with Adrien Broner ... and he looks pretty good!
Tha Boss was throwing some decent jabs, some combos and a hard right hand ... even knocked Broner's mitt right off!
Not saying Ross is ready to take a pro fight or anything ... but he's moving pretty well -- especially after recovering from a medical scare back in March.
Broner's last fight was back in April -- when he fought to a draw against Jessie Vargas. There are reports the two are closing in on a deal for a rematch.
Meantime, why not train one of the biggest names in all of hip-hop, right?
