I like both workouts, BUT I modified IMAX3 a lot: no jumping to the floor from the step (when did that become safe for most people?), I step down; for plié jumps, I do 3 pulsiing plié's followed by one jump on the first set (while they jump every one), the do every other one on the other sets.
On the move where they leap to the end of the step, then across, then jump turn, tuck jump and two ricochets (I HATE ricochets: to fast, too much possible torque), I do a "two 'frog jumps forward, two frog jumps back, over the step, turn step" and end up in the same place they are at the end of the sequence. I figured out that last substitution the first time I watched the workout and decided that there was far too much impact to be safe, and that move in particular was a bit ridiculous as far as impact.
