Starting out think about the most basic of exercises, walking. I was walking 3 miles a day early in the mornings and then working weights in the afternoon. When you can manage walking even a mile at a fast clip you'll find you stamina for the other exercises greatly improved. Try Irish's idea to begin with maybe adding in variations as you get more wind. Pushups with your feet propped up some, leg raises to compliment the situps. I always found dips to be great for arms too... you can even add weights to a belt as you advance there. If these ideas don't thrill you... maybe do a search on isometrics.. another free source of fitness my brother used back in his martial arts days. Good luck with whatever you do. Just more rambling thoughts from me.
