I have six months to shape up?

In six months my bf comes home from the Marines i want him to see that i am a different person so we can start our relationship all over. I also want to shape up and tone my stomach and arms. Any suggestions?

Run. At least a mile 3-5 days a week. Ive done it and lost 30 lbs in 3 months. Think what you can do in 6!! Anyhow, run and then do some wight training 3 times a weeks for about 30 minutes.
That should do it.
also, eat breakfast, a snack, lunch, a snack, then dinner and a snack. try to keep it under 1200-1500 calories a day. You'll look and feel great!! 3 months, watch!
