Re: Need help with shaping up after illness...
I'd just increase the incline. As high as you can comfortably go. Increasing speed just makes it more of a calorie-burning exefcise, which isn't your goal. 6 days a week is a lot. 5 maybe, or every-other day so you get a day of rest in between sessions.
