Summarize the following:
Using a trampoline can be very dangerous, so it is best to train first in a safe environment. Training happens in lessons for competitive sports including gymnastics and diving. There, a teacher or coach can help you learn how to use a trampoline properly. Improper use of a trampoline can lead to severe head and spinal injuries. Flipping increases your chances of this. Flips should not be attempted until you feel completely comfortable using a trampoline. The ideal area to place your trampoline is a level surface away from any obstacles, including trees, fences, and lawn equipment. Place the trampoline on absorbent ground such as a grassy lawn, wood chips, or sand. Add padded mats for extra protection. Proper cushioning shields you when you fall. The motion and momentum from flipping makes bone fractures more likely. Safety padding is brightly-colored shielding that goes around the edges of the trampoline, covering the frame and springs. Order padding online or choose a trampoline that has the thickest padding possible. The frame is a hard surface and can also cause fractures if you land on it. Never get on the trampoline until you have ordered a net and placed it securely around the trampoline. When you fall, the net will slow your momentum or catch you before you hit the ground. This is important in flipping because of all the movement you'll be doing. Bigger trampolines have enough space for more than one person, but this isn't safe. Besides the difficulty in controlling your motion when multiple people jump, the other person can easily bump into you and send you flying. The lighter person on the trampoline is more likely to get hurt. Jumping off while flipping creates a heavy impact that can damage your knees and break your ankles, but this applies to regular jumping too. Instead, stay in place until you come to a halt. Walk to the edge of the trampoline and step or slide off.
Get supervised training first. Choose a cushioned area. Install safety pads. Enclose the trampoline in a safety net. Limit it to one person on at a time. Don't jump off.
