That's always my question -- but then, have I started doing it? NO! I mean, not yet ;)
Well, I found this video shared by a friend in Facebook and I think, I can just watch. It's really hard to lose weight especially if you're working home. For me, I always go out, walking towards the supermarket, instead of commuting. It's better that not doing anything, eh?
If you think you can spend just 5 minutes of your time to do this CRAZY exercise, think again...and watch..
