PLUS, Martial Arts are very expensive. At least the classes I looked into around here are.

Tae Bo is a good way to get in shape at home.I taught good 'ol fashioned kickboxing at my gym a couple of years ago (with punching bags, gloves etc), and when I tried Tae Bo it was too easy, so I had to put on hand weights. Actually hitting or kicking something is a much better workout, but hard to do at home (husband got tired of holding pillows for me to hit, so I finally got a water-weighted portable training bag for the patio...).
