If you want high intensity and high impact, go for IMAX 3 (my favorite)! The recovery blasts in 3 are shorter than in 2 which makes it really tough and challenging. I like the choreography better in 3 (a little more complex than 2) but doable. If you have Low Max, she does the same reverse mambo off the step in IMAX 3.

Welll...I can say this you ladies definitely didn't make it easy I know that for sure lol I think I'm gonna go with Imax 2....I'm a little worried about the shortened rest periods in 3, as well as the choreography being a little more to get right away. Concerned I'll get burned out and then never use it So....thank you very much for your help, hopefully I'll love it so much I'll go ahead and get 3 soon anyways!
