Not much - I did Chalene Xtreme before I took over the basement room for my home gym :bigsmile and I did it in my bedroom - in a small space between the bed and the wall....As long as you have enough space to lie down for push-ups, and can move your arms or do a lunge/squat without bumping into a wall, it's fine....

Not much space at all! The most space you'll need is for the pushups, workouts on your back and then possibly when you do the moves that require you to double the distance from side-to-side. You will love CLX though!!

LOL for the UPS man - I ordered a set of kettlebells (altogether 60lbs) from amazon....The look on the guy at the mail services place when he gave it to me was priceless - and even more when he offered me the use of a dolly to get the box to my car...I thanked him, declined his offer and hitched to box up into my arms (hoping I won't fart or drop it on my toes....that was after Chalene Xtreme, so I did not - but it was hard to carry it outside and not giggle like a school girl looking at the poor guys face... ! ;-)
