Get on all fours in the foot well facing the door. Everyone’s first instinct is to put their hands or legs down first. That’s the worst thing you can do: you will break something. The pointy parts of your body hurt – elbows, knees, hips, ankles. Put your fists under your chin, and bring your elbows together. Keep your chin tucked in to your chest to protect your head. The best point of impact is the back of the shoulder and your back. If you dive out directly onto your shoulder you’ll break it.
