How To Fall Backwards (Safely)
Falling backwards can result in serious injury if you don't know what you're doing. To protect your head, make sure you keep your chin tucked and try to fall in a way that keeps your head away from the ground. Falling diagonally helps accomplish this. Rotate your body to dissipate the impact of your fall to a larger surface area. Make sure to use your arm and hand to break the fall.
Exercises to strengthen your upper body and lower will help you fall without injury. Be sure to build up enough strength and stability so you can absorb impact without serious injury.
