|: : I don't have a trampoline or mats or anything like that.
I just realized that you said no access to "trampoline or mats". Many times, resale shops have exercise mats for cheap. If you have free community centers in your area, that might also be a good source for exercise equipment, and some even have trampolines!!
Ask all of your friends too, and see if any of them know anyone with a trampoline. Become friends with them.
