oooh...i know a great one for thighs. The wall - sit. put your back up against the wall and and bend your knees, stay that way for at least 3 min. do it about 4-6 times a week. also, the good old squat is great for thighs. do about 20 of those every day, and they should be toned in no time. I know how you feel. I am 5"7' and 234 lbs. i used to be at 252, but by working out more i have lost a lot in about a month.
