Systema: Falling backwards 

Best wishes from the team of Transition CRT

+Richy Parton Thank you for the compliments. We are glad you enjoy our instructions!

The first thing to learn is how not to hurt yourself falling. It makes more sense to have the option to roll or not since you don't know where you will be or what direction you may need to move in. If you can't roll back because of an obstacle, being tackled low, or a drop behind you, only having a roll to work with could make the situation worse. That said, I do love a good roll out of danger. One important thing to watch with rolls is your awareness: keeping an attacker in peripheral vision, not getting dirt in your eyes, and getting up in a way that doesn't make you vulnerable.

Heels in sky = western spy

Good question! Depending on your situation (for example your gear) you will always have to adjust your way of moving. Some combat boots will definitely deny you to squat all the way down with your ankles like we show in the video. In that case you might squat less deep.

Transition CRT in Strong on Defense, he suggests supporting the heels. I guess it depends on what you wear to work, da?

It isn't a judo maximum surface area technique as much as it is about letting kinetic energy escape out the arms instead of reverberating around inside the body. Certainly it could be a bit narrower and work too.
