Go where? Your profile says you work "in the house." Does that mean you work out at home and you cant get down to the basement or wherever?
At the age of 22, I am going to presume that you cant afford a personal trainer. Cuz if you can, hiring a PT is the best thing you can do. Not just for motivation, but to get started right.
Here are some suggestions:
1) move a set of dumbells to wherever you sit and do some simple curls while you are sitting there wishing you would go downstairs. Maybe once you feel some pump, you will want to go and start working out for real.
2) join a class in aerobics or whatever at the Y and let that get you moving and in the habit of exercising again.
3) go to the bookstore and look thru these two books. You will see what effect being overweight or just having fat, esp around the mid section, has on your health. Understanding what is going on in your body can be really movtivating because you know WHY you are working out. I know you are not "old" yet. But it never too early to get in shape and keeping your health.
