Question

   

Have you ever jumped on a trampoline? Today many people use it for exercise.

Back in the 1980s, researchers found that jumping on a trampoline was a good way to help astronauts regain their strength. Actually, trampolining has many advantages. It helps bones and muscles grow and improves your balance by stimulating the inner ear. It is especially useful for increasing flow of the lymphatic system, which helps your body get rid of harmful toxins. Trampolining has benefits similar to those of running, but without too much stress on knees and ankles.

If you would like to start trampolining, you may first need to ask a doctor to make sure it's a safe activity for you. It's easy to find an inexpensive trampoline, but it should be well­made and strong enough to support your weight. To avoid accidents, some trampolines have a safety net around them. Remember: whenever you are on a trampoline, be careful not to jump near the edge of it.

Here are a few exercises for beginners：

●High Knee Lift. Raise one knee at a time. Lift your knee higher than you usually do when you are running.

●Star Jump. Jump into the air and spread your arms and legs into a star shape. As you gain more confidence, practice more difficult levels.

●Tuck Jump. At the top of your jump, bring the knees to the chest, with the arms holding the legs.

●Pike Jump. Jump high, bring the legs up, and point the toes forward. Touch your toes with hands.

There are many more exercises you can try. Happy trampolining!
