I use to run cross country in high school I weighed 285 my freshman year and ran 2 miles a day. My goal is to get up to walking 5 miles ever morning then I will start adding some interval type jogs in there till I am running 3 out of the 7 days.
I have found with walking that if I even take a day off it gets harder so walk everyday. Sundays walk is a little shorter and more relaxed but if I don't walk at all monday I get sore faster and winded quicker.
