The football boys seemed to cheer each other on when they were doing good rather than when they needed support when they weren't doing as good.
The boys also did an activity where they ran opposite ways to see who was stronger. Whenever a boy noticed that he was loosing, his body language changed and they seemed to not care anymore about how they did.
Each station required the boys to use a different strength. To top it off, the last activity we saw required them to use both their arm strength and their stamina. You could tell which boys were uncomfortable doing this activity because of their body language.
