In reply to Denni:
If you want to go down the 'cardio' route (and I use that phrase lightly), then buy a decent skipping rope. There are loads of drills you can do with one and it can be entertaining.
If you want to get lean, chiselled and 'look good nekkid' get yourself a barbell and 150kg in plates, then cycle through phases of 5x5, Wendler 521 and RPT training using exercises like the deadlift and squats.
You WON'T get big (unless you are in the genetic elite), and if working with sufficient intensity (you should be training hard, not watching TV), will be done and dusted in 30 minutes two or three times a week.
However if you want somewhere on which to hang clothing then get an exercise bike/X trainer/rower.
