Pay attention to protect your neck when you get off the trampoline, because it is very easy to twist and it is very harmful to your spine.
However, trampoline is still a very good exercise on the whole. Jumping for ten minutes is equivalent to jogging for half an hour.
For obese people, this is a very good exercise to lose weight. The general price of trampoline ranges from 1000 to more than 3000, depending on the region.
