What's the name of the workout video series starring Richard Simmons?

In the days before Extreme Makeover: Weight Loss Edition, there weren't a lot of options for those who wanted to take a journey from not-so-fit to more-fit — gyms were mostly geared towards people who were already in good shape. Richard Simmons, who had been heavy as a child and lost over 100 pounds himself, noticed this.

So he started his own gyms and designed workout programs that were accessible for pretty much anyone.

Most recently, Richard Simmons made headlines by suddenly spurning the spotlight and living a more reclusive lifestyle — to the point where speculation ran rampant in tabloids that he was being held hostage by a housekeeper. Turns out, he's apparently just fine.
