JK....you're doing good.....you've turned the corner and this is the toughest point, you can keep going and it will get easier, or you can go back and be defeated......so far it looks like you're gonna beat this. You put in a solid week. You upped all your lifts and are up in bodyweight. Just repeat for this week. One week is already in the bag.
You'll get out of the obsessive cardio mindset when you see your lifts rising and your body growing muscle....you're already well on your way.
I'm proud of you , man.
About the car....that stuff sucks, but it is just life getting in the way, sometimes good, sometimes bad.....If you look into something pre-owned, but only a year or 2 old, you can do well on $300/month or so.....you can probably buy a nice '05 or '06 Durango or Trailblazer. I used to think the Ford Escape was a 'fluff' SUV, but I rode in one and they are pretty solid and in the age of gas guzzlers are a good buy, and you can probably more than likely go brand new for under $300/month. I hear ya on the Corolla and Civic, GREAT cars, but they aren't me either...If u wanna ditch the Avalanche over gas, you could look into cars like a Grand Prix or something.......what are ur plans for Labor Day?
