IMO, there will never be NO challenge. It is always going to be kinda hard. When I am feeling pretty strong is when I add risers. I am more likely to add risers to my step for SJP, or Step Blast, Rythmic Step rather than for, say, IMAX 1 or 2. Try adding a riser to the "easier" Cathe step tapes. Personally, I feel risers are overated. But, I am also 5', so anything higher than 6" really feels akward....
