Rebounders are different to going on a proper trampoline. You can just do a gentle bounce without taking feet off the surface. They have so many health benefits, and are excellent for your lymph system. I wish i could use mine more, if i still get neck pain from it, maybe i'll buy a better quality one.
I think my husband said his neck hurt after using it, so maybe it is the rebounder at fault. They do say not to get a cheap one, but then they would, wouldn't they. lol
