Trampolines are awesome, not just for kids. Best thing I bought (long before I had own kids). I recovered my knee after an operation with it - the "professional" reha I got before was close to useless.
Because you cannot just mind and recklessly jump on it - you have a generic flat/bouncy ground to do all kinds of soft movements, you can do slow or fast. So recovering I did not by jumping yet, but by roling and softly bouncing up and down. First while lying, then standing ... then finally jumping again.
Now many years later, I bought a second, connected them and can do longer jumps and tricks between them.
Oh yes, and the children now love it since they could crawl in it. (Except with strong sun, my older boy is strongly afraid of the static electricity that builds up, that can result in discharges strong enough to hurt, which my daughter uses intentionally to shock him).
Of course it helps, that the Trampolin is hidden from view, not sure if I would have as much fun it it, if everybody from the street could watch. If you have that, or don't care, - go wild in it. Extremely rewarding sport for me. I never hurt myself in it, but that can of course happen, if you overdo it, but compared to the accidents I had in all those other sports that not happen on a soft ground ...
