I found the easiest and earliest level you can get this on is USA 5, about a quarter of the way through the level after some swinging hammers you'll come to a section with a group of 10 or so fans under a platform, these can easily be passed over without risk of falling but if you do mess up there is a checkpoint just before the fans.
Here's a video to demonstrate how i did it. (Area is at 0:40)
