Imax 2 vs LowMax: anyone burn fewer calories w/Imax 2?

[step_a_holic]

I just did Imax 2 for the first time with my Polar F4 HRM and burned less calories than I do with LowMax. I burned 537 (including cooldown & stretch) vs 633 w/LowMax (not including cooldown & stretch).

I'm just really surprised. Curious to see if anyone else has any similar experiences.

I thought for sure Imax 2 would beat out any other workout...guess not. That's not to say that it doesn't kick my butt though!!!

Low Max is about 20 minutes longer than Imax2, so that might explain the difference.

Ahhh, didn't think about that! That does explain it.
