The first time I tore my meniscus was from repeatedly getting up from falls in an improper manner. This information is absolutely critical, and I salute you for making a simple video showing ways to do it right.

wow! excelent! thank you very much!!! very useful video.

Good solid ground work. Makes me want to experiment sword in hand.

Personally, I'd really like an in depth tutorial, but I understand it if you don't have time for that.
