Do you know the most important thing you've missed in this video?
It is not a man struggling and torturing himself to carry a plus-size woman through a contest. No.
It is that this video is a visual representation of what happens when you, a man, carries more responsibility than the woman in a relationship.
In this video The woman being carried is big enough and, by appearance, ought to have enough strength to overcome her visibly average-sized opponent. Yet, as we see, she loses the contest and exhausts the man carrying her in the process.
Why?
Because, considering it rarity,(as she's a plus size female who no man ever attempted carrying) being carried became more important and enjoyable than winning.
The comfort of having someone else bear the burden can, if one is not careful, become an end in itself. The effort shifts from solving the problem to preserving the arrangement.
This happens in real life too.
When you take on too much of a woman's responsibilities, the result is often not gratitude or growth but dependency. You carry and grow weary, while she slowly forgets how to carry herself.
Point is, if you do too much for her, be careful that your kindness does not become her substitute for effort. It often does.
And the bigger implication is she grows comfortable, and you tired, and neither of you reaches the finish line.
Goodluck. Or, congratulations.
