The "Brady Bunch" star, 69, candidly detailed the intense preparation he goes through in his daily workout routine while he participates in "Dancing with the Stars" season 32. 

"For one thing, it's seven days a week. For another thing, I do a complete workout … stretch and practice before I come to rehearsal … that’s new," Williams explained to Fox News Digital.

"I try and channel Florence Henderson, who encouraged me to pursue an invitation for ‘Dancing With the Stars,’" Williams told People. "Being familiar with my theatrical background, she felt that I could do very well. And at that time, she had just been eliminated and asked if I would carry the torch."

Henderson appeared on the show's 11th season in 2010. She passed away in 2016.
