Richard Simmons, legendary fitness guru, dead at 76

Legendary fitness instructor Richard Simmons has died, according to a report.

Simmons, who turned 76 Friday, died just 24 hours after he thanked fans on social media for their birthday wishes.

The health guru, who stepped away from the public eye a decade ago, rose to fame in the 1970s and ’80s after opening several gyms across the country and releasing his iconic  high energy fitness tapes.

His death was first reported by TMZ. Police told the outlet they believe it was a natural death.

Simmons revealed in March he had been diagnosed with skin cancer.

In a rare interview with People Magazine this week, he said he “feels good” despite his age.”I am grateful that I’m here, that I am alive for another day,” he said. “I’ll spend my birthday doing what I do every day, which is to help people.” 

The “Sweatin’ to the Oldies” star had announced earlier this year he was planning to open a Broadway musical with renowned producer and composer Patrick Leonard.

Simmons was beloved, and often parodied for his flamboyant, positive attitude that helped millions of Americans get in shape for decades.
