Input:
I used to drive almost an hour (each way) to go to a Sky Zone 2x a week to work out on trampolines.  I loved those classes and they were fantastic for me because it never hurt any of my joints but gave me a better cardio workout than I had ever had.

I have been both a walker and a runner but my body can only handle that once or twice a week so now I can get the benefits of both in the comfort of my home. And so much fun!! I hop on the trampoline just because it's sitting there - you can't do that if you have to lace up your shoes every time you want to exercise.

A note on setting this up.  I am a 41 year old female and was able to get it together by myself in about 15 minutes.  The key is to get the regular joints (without the lip) put together first, kneel on that edge of the trampoline to hold it down on the floor keeping the other 1/2 standing up, set the smaller part of the joint on top of the lip on both sides and then push down (like you're lying down on your stomach) until they slide in.  It is stretching the trampoline out so you do have to push with all of your weight.  Make sure you keep your hands at the top though and not anywhere near the joints.

Thanks to everyone who helped me make the decision to get this!
