I don't have access to a stair master, but my appartment building has a set of stairs at each of the four corners of the building, 10 flights each. Is twenty minutes walking up and down the stairs a good idea? Should I lunge and skip over a step (so instead of going up one step at a time, go two steps at a time). I really want to work my glutes (ass muscles).
