I think it is nice that you are so focused on going there.
For me I do:
Crunches with a twist (like scott said) about 100 of those
Pushups about 50 in the morning and 50 at night
then I go for a 6-10 mile run at about 5am.
Even though I destroyed my growth plate in my ankle I still work out to keep myself in shape
Try starting small with multiple types of workouts try running around your block once or twice in the morning.
