Joey Kovar -- the muscle head from "Real World: Hollywood" and this season of "Celebrity Rehab" -- has found a new way to keep off drugs: body slams, suplexes and sleeper holds.
We spoke to Jimmy Blaze -- who runs a wrestling organization called POWW Entertainment -- and he tells TMZ Kovar has already begun his training regimen with the company ... and will start wrestling for POWW in a couple months.
Blaze says the plan is to get the reality star/recovering addict in the big leagues ... starting with a contract with TNA -- Total Nonstop Action Wrestling -- on Spike TV.
The reason for TNA in particular? We're told it's because Hulk Hogan just signed with them -- and the Hulkster is Kovar's biggest hero. Awww.
