They are very helpful to make your body parts safer when on the terrain.
For the strength, stay hydrated as you need to have a healthy body that could endure the pressure of the activities. Stay fit so you can be able to do the activities. A strong body and also a maintained equipment is good as when your equipment would malfunction, an accident can happen. Check the etiquette that is written so you can follow. Have a regular exercise if you can so that you can prepare for the strength that is needed.
A helpful one to learn is know how you can allow your body to fall into a better position than what it should be. Falling cannot be avoided sometimes but the initial reaction to falling is to hold onto something.
