Few gyms around the world carry the notoriety of Arlington’s Metroflex in Texas, home to eight-time Mr. Olympia Ronnie Coleman and a number of other top pros. Its unique hardcore appeal, the antithesis of today’s air-conditioned gym factories, was on Big Ron Partlow’s bucket list, so MUTANT on a Mission paid respects to this landmark iron hub. Owner Brian Dobson shares its 32-year history before Big Ron joins locals Zach Wilson and J. Warren for a drenching, midsummer back workout in which Ron lost 3 poundsof sweat. But what’s most memorable was what he lost after his training session! Warning: Not for the faint of heart!
