home gyms, what equipment?

ok my sisters finally f-cked off into her own house (yes!!!!) and i've claimed her room, now my room is spare and im turning it into a tiny gym for myself. i already have an exercise bike and weights.

what else do i need, bare in mind this room is only about the side of 2 normal beds. i was thinking a bench and a mat to do situps on.

you should get a stereo and a fan. are your rooms back to back? if so make a hole in the wall and pass some phonos through and take an audio feed from your pc. easier with mp3's than cd's.

a bench and loads off dumbells

if u get a basic bench press system with leg curls and a tread mill can u hav an effective gym?
