Though expensive, it is a great workout if you have the room to jump around and will stick to it.

I told myself I will not join a gym or buy anything related to exercise until I am consistently doing push-ups, sit-ups, and either walking or running. (Haven't started yet).

Losing weight is actually easy in theory. Burn more calories than you take in. Or in other words, move more/eat less (or better).

P90X is a killer workout. You almost have to get in shape before you go through it.

Best wishes! As long as you are doing SOMETHING, you are better off than sitting on the sofa stuffing cookies and watching t.v. (like me...)
