It gets easier as the days go by. I cut alcohol intake to 2 beers on Sunday (which may go up to 4 for Football) but within a 2200 calorie day. With some sort of exercise during the day.
Is the caloric burn for the incline as high as 'going faster'? What i'm doing right now is intervals where I walk for 2 minutes at 4.0, run at 6.5 for slightly over a minute till the eight minute where I interval walking and running every minute. However, if the burn for the incline was greater than that I'd absolutely give it a shot.
