Brady Bunch actress Maureen McCormick, 60, is pushing her body, mind and emotions to the limit while competing on Season 23 of Dancing With The Stars.
These candid photos were taken after a rehearsal in Los Angeles, California, on Saturday, September 10, just two days before the show's premiere.
A witness tells the Dailymail.com: 'She looked completely exhausted. It's obvious she's putting her whole heart and soul into this competition.
'I just don't know how she will be able to keep up this pace and compete with Olympic gymnasts and other pro-athletes.'

On last night's premiere episode of the hit ABC reality show, McCormick, 60, teared up and rambled on in front of the judges after her first dance (a Viennese Waltz) with pro-partner Artem Chigvintsev.
Her former sitcom mother Florence Henderson, 82, was front and center watching her perform, and warmly embracing her afterwards.
McCormick played iconic Marcia Brady on the Brady Bunch from 1969-1974, and later starred in The Brady Brides in 1981 alongside her TV sister Jan, Eve Plumb, now 58, in 1981.
But her life has been far from a sitcom. The actress wrote an eye-opening tell all in 2008, titled, Here's The Story: Surviving Marcia Brady and Finding My True Voice.

The best seller chronicled, among other things, her descent into addiction, trading sex for drugs, crippling depression, and a battle with bulimia.
She now lives a quiet life outside Los Angeles with her husband of 31 years, Michael Cummings, and their 27-year-old daughter, Natalie.
In 2007 McCormick joined the VH1 reality show Celebrity Fit Club, and went on to win the competition by dropping 38lb from her 5ft, 3in, frame.
Two years later, she had packed back on all the weight and and then some before working with a trainer to get back to her goal weight of 125lb in 2011.
Last year, in 2015, she competed in the Australian version of I'm A Celebrity... Get Me Out of Here, where she camped out with fellow celebrities, ate bugs, and revealed that she used to date Michael Jackson.
The couple danced to (You Make Me Feel Like) A Natural Woman by Aretha Franklin before speaking to the judges

A source close to McCormick told Dailymail.com: 'Maureen is not new to reality TV, but Dancing With The Stars is far more intense than her previous gigs. In just a few weeks they will have to do two dances per show.'
One thing is for sure: McCormick is bound to have the nostalgia vote from all of those fans who grew up watching The Brady Bunch.
Millions of boys had crushes on her growing up, and millions of girls wanted to be Marcia Brady.
Who can forget Jan Brady bemoaning her gorgeous older sister with 'Marcia, Marcia, Marcia', or Marcia swooning over teen heartthrobs Desi Arnaz Jr, and Davy Jones?
