When I was in what I considered my topic physical shape I ran two miles a day either in the morning or at night, I did a 40 to 60 minute circuit routine at the gym starting with the stationary bike and ending with crunches and machines that focus on the stomach area. As for the diet I didnt pay any attention to the bad things I ate because I was drinking a gallon of water a day which seemed to clense everything.

For the cats who want to jog this is old advice but it works start with walking or jogging/walking short distances and gradually increase the workout until you reach your distance goal for jogging. I started with 1 mile in the morning and kept at it, eventually I found myself jogging 5 miles a day.

Start small with everything and increase gradually. Thats the best tip I can think of for finding your own routine.
