Best workouts for abs/chest? Options

[cnelson]

Alright, well heres the story; Since the end of novemeber, I have lost about 65 pounds. I went from 225, to 161 as of this morning. Yes i do eat in case someone asks that question. I have lost weight before but never to this extant. Now i would really like to start working on toning my body. Mostly my abs/chest muscles. I know doing sit ups and push ups is probably the best.

It needs to be something that i can do at home, i don't have time to get to a gym. Although i do have a weight lifting set with a bench and stuff, its not set up right now.

But if just continue to do, sits up and push ups. How many should i do, how much should i increase it, etc?

Right now, i'm doing about a 100 sit ups and a day and 20 push ups. I'm 18, and in decent shape. Don't know if that helps or not.

But thanks for any advice guys.
