Yes but many people will need to "train a little" to be able to walk for 30 min without stopping for a breath. Same with cooking pancakes, or programming.

I think my idiomatic phrasing of "some" is probably the problem here, so let me be more explicit. For me (and many other people), I would need to train a lot to run for a mile.

As I am in fact currently training to run, I can tell you that it has taken me two months so far to get to a stage where I can only walk/jog for twenty minutes, not yet actually run a full mile in one go. I expect to be able to do that at the end of this month.

It is not level one.
