Swing out and turn around (or do the trick after making a return from a catch). As you swing towards the platform, a (close) friend stands in the middle and braces themselves with the platform supports.

This is one of three tricks that makes up the 'Dirty Susan' sequence invented by Susan from Denver.

Thanks to Susan for inventing and naming this trick.
