As long as your ceilings aren't really low - the trampoline is raised about 8 inches so when you're jumping if you get too enthusiastic you could bump your head
- the mini trampoline would be a good cardio option.
You can march and do high knees or do a run in place jog or just jump on it. The thing I liked best was that it was easier on the joints rather than running on hard pavement. I love mine too - it's one of my favorite pieces of at home work out equipment.
Put some good songs on the IPOD and crank out a good routine.
Oh and it does have rubber feet on the legs so it doesn't make a thumping noise when you're jumping on it in case you were wondering if it would disturb the neighbors downstairs. When you're done with it you can lay it flat against the wall - might be a bit too high to slide under the bed. And it's a big hit with the little nieces and nephews!
