American bodybuilding icon Tom Platz, 68, shows off insane thighs as amazed fans claim he’s ‘still the quad father’

BODYBUILDING legend Tom Platz may be past retirement age, but his thighs remain reminiscent of his glory days.

Platz, who is now 68, showed off his amazing thighs in a social media post.

He posted on Instagram to offer birthday wishes to his wife, Dr. Cha Dikito-Platz.

Naturally, fans had their eyes drawn to his extraordinary legs and thighs.

"Still the quad father," one fan wrote in the comments section under his post.

That is a reference to the nickname "The Quadfather" which Platz has had for decades.

"No way his legs still like this," another fan posted.

"How are u still ripped, amazing!," another person wrote in the comments.

"The fact that your legs look like that still is insane," was the comment from another poster

Platz became a household name in the 1970s and 1980s.

He was also known for his leg development, which in his prime measured over 30 inches.

He has trained a number of other bodybuilders, including Germany's David Hoffmann.

Platz competed in seven Mr. Olympia events - that is an international bodybuilding competition held annually - and finished third in 1981.

Naturally, Platz's incredible legs are down to an immense exercise regime.

Those exercises have traditionally included back squats, leg curls, and calf raises.

Platz recently revealed that Arnold Schwarzenegger provided his career with a real boost in the 1980s.

Before becoming a mainstream movie star, Schwarzenegger was a professional bodybuilder and at one time a rival to Platz.

Despite that, he gave Platz a welcome helping hand.

"After ’81, Arnold was going into acting more and more," Platz said.

"He goes, ‘look I want to have everybody contact you, because I’m going into the movies and films, and I’m busy doing that. Is it okay?’

"So I’m like, ‘yeah sure let’s do it.’ They’re like getting 10,000 to show up for the half a day! I’m like ‘holy smokes'.

"It was like he opened that door for me. He’s a ruthless kind of guy, but he’s very generous.”
