You dont clearly state your current fitness level so its hard to give any accurate advice with regards to physical training.

As a safe option, go for 1 hour of running per day, steady pace (Heart rate at 140-150 bpm). If you dont have a monitor, run for 10 minutes and stop and take your pulse. Best place is below your ear just under jaw line. Count for 6 seconds and add 100, so if you get 12 beats in those 6 seconds its roughly 120 bpm so you know you need to speed up a touch. Continue running for another 10 mins and re-take etc until your running at the correct pace.

You should incorporate a resistance training program but there are too many variables to give any sound advice
