Walking the best exercise?

Thanks everyone for your replies! I guess I'm going to just stick to walking for now, and then the other exercises for toning after this weightloss later

You should tone while losing, as well. Walking it great cardio and will certainly build leg muscles and even work your abs a little. But why wait to start to weight training? You may not SEE it until the fat is gone, but at least you'll be ahead of the game if you start now. Do your cardio and then maybe 20-30 minutes of weight training two or three days a week if you don't want to commit more time.
