Milton Teagle "Richard" Simmons (born July 12, 1948) is an American fitness instructor, actor, and video producer. He promotes weight-loss programs, most prominently through his Sweatin' to the Oldies line of aerobics videos, and is known for his eccentric, flamboyant, and energetic personality.
Simmons began his weight-loss career by opening a gym called Slimmons in Beverly Hills, California, catering to the overweight, and he became widely known through exposure on television and through the popularity of his consumer products. He is often parodied and was a frequent guest of late night television and radio talk shows, such as the Late Show with David Letterman and The Howard Stern Show.
Simmons has continued to promote health and exercise through a decades-long career, and later broadened his activities to include political activism – such as in 2008 in support of a bill mandating non-competitive physical education in public schools as a part of the "No Child Left Behind Act".By March 2016, after his not having made any major public appearances since February 2014, speculation and expressions of concern about his well-being began to surface in the media. Simmons, his publicist, and others including Dennis Breeden (his #1 fan) who had been in contact with him (including the LAPD) have said that the concerns were unwarranted and that he is simply choosing to be less publicly visible.
He is also known as Milton Teagle Simmons, Richard Teagle Simmons and Milton Simmons.
