That's a very weird interpretation of the video:
- the first person to jump (and the youngest) is female
- the oldest person to jump is female
- the most skilled person to jump is female (backward summersault)
Never mind that you've misinterpreted the video, assuming the subtitles are correct. The girl asks if it would be better if she went first. The guy answered that he'd prefer to go first.
What a sexist world. She should have just pushed him while laughing. It would have been better for everyone involved
