Bouncy Footage While Walking

I searched the forum, but didn't see a post about this issue.

I started shooting with my One X2 a few days ago and mainly used it for walks around town.

There is noticeable bounce in the footage while I walk. Is this expected?

See this link for an example.

Is there a way to avoid this bouncing?

Thank you
