I will lose to win!

I came across this site and decided I should sign up. Upon doing so, I found out I signed up for it back in 2009! At that time i weighed 197lbs, before my second child. I'm 5'10" and currently weigh 204lbs. My goals are as follows-

1st goal- 190lbs
2nd goal 170lbs
Final goal- 145lbs

I'm excited to join all of you, and am ready to do this!
