The trick worked.

In a gym, a man and a woman perform a synchronized exercise where the man squats low while the woman balances on his thighs in a plank position, then they extend their bodies into a horizontal line, with the man raising one arm. In a home setting, a man and a woman perform a similar exercise, with the man squatting and the woman balancing on his thighs in a plank, then extending into a horizontal line before the man flips backward, causing the woman to fall.
