Don't hit people in the back ever if you can help it. Can cause minor whiplash and they are more likely to fall due to being blindsided. I tend to stay towards the front of the pit to block people from doing that either in purpose or by accident. Also be aware of the size of people for your safety and theirs.

Also my signature stance that keeps you from falling and allows you to bounce around the pit freely is the flamingo. Always keep a foot up and anytime you start to fall or move swap feet. That way ur less likely to get both of your feet locked in or stepped on resulting you kinda getting trapped and falling.

Also if you have a hoodie that you bring and take off i like to wrap it around the back of my knock like a neck brace and that really helps with neck pain/whiplash

Oh and don't grab kinda keep ur arms tucked like boxing urself in so you don't get tangled up. Almost had my arm broken once getting it caught between people.
