Gordon Ramsay is JACKED, SON!!!
The "Hell's Kitchen" chef was out in Malibu on Tuesday ... strollin' around in his workout gear after a triathlon training session -- flexin' a serious pair of guns.
Turns out, 48-year-old Ramsay is a hardcore athlete ... he's completed 15 marathons, 3 ultra-marathons, 3 half-Ironmans and the actual Ironman in Hawaii.
FYI -- Ramsay started running marathons in 2001 ...and says his goal is to break the 3:30 mark.
In fact, Gordon clocked in a time of 3:30:14 back 2004 ... but says he chocked that up to posing for pics for fans and signing autographs.
"Had I not said yes and taken some water and stolen a Jelly Baby, I would have done it in under 3.30," Ramsay told The Telegraph ... "I am going to break 3.30. I won’t stop until I do."
