I agree with Patricia: I think IMAX 2 is a bit more difficult than IMAX 1. If memory serves me correctly (and how sad if it doesn't, since I just did IMAX 1 last week!), I only had to modify one of the intervals. There's a couple in IMAX 2 that I tend to modify. In either case, both of the IMAXs are kick-butt workouts that can be conquered with time and practice. Have fun kicking back!!
