Another way to teach in a back chain is to teach starting from the end without doing the first parts at all

Teach only the last part (tag), then teach 2nd last part (tag). Put them together etc. This is what was done in the high jump video. You may have seen it before, but watch it again and see how it’s almost completely back chained. This is a different edit of the video than you have seen before, that highlights the back chaining elements.
