best bit of indoor kit for cardio?

[MellowAutumn]

Had to get rid of treadmill as just too huge, want to replace but not sure what with. Any suggestions ? Needs to be fairly storable, and preferably for cardio and all over body conditioning.

Hoover?

TV/iPad/PC/laptop i.e. anything that will play YouTube videos or DVDs!

(Sorry not trying to be a smartarse, just think you really don't need equipment for cardio, just your own body.)

I think a spin bike might be good? They seem pretty solidly built and nothing electronic to go wrong.
Mind you I'd want a heart rate monitor to measure workout intensity!

I second a fitness video.

Assuming you have a bit of space, a skipping rope... there's a reason you see boxers in films training by skipping, it is really hard!

Thanks - I think a video and skipping road are great ideas and certainly a lot cheaper the rower's etc I have been looking at
