Let me preface this with: I
Amy Bento step workouts! IMHO, you just can't beat her for complex choreo and intensity.
I really love #3 - really a lot of fun, the energy is great, the music is good, the choreo is fun. One of my favorite things about #2 and #3 is the she includes "Power Ups" - short little blasts you can add on. She even has premixes with the power ups included - once you get the combos down, these are a lot of fun and good way to mix it up and add some intensity.
#4 was probably my least favorite of them all. I am not sure why - the background was kind of dark and cramped, but I can give that a pass typically. The routines aren't bad, and I do reach for it occasionally but not nearly like the others. There are power ups, but the premixes including them are not as fun as #2 and #3.
I definitely enjoyed #5 as well. It is complex, for sure. It took me awhile - there is a tutorial on this one which I think helps a great deal in getting the combos down. Once I got them down, I did enjoy this one. One other thing that I actually like on this one - there is no stringing all of the combos together at the end. Now while I do wish she had a premix that included that, it is a refreshing choice for when I just can't handle any tift'ing whatsoever.
Stepletic is pretty awesome! It represents a shift for Amy in three things: one, the workouts are shorter than her usual, both clocking in @45-50 minutes with warm up and stretch; two, she has two completely different step routines on one video(!) and, three, she offers a lovely 10 minute yoga stretch as an add-on. This means you can get your step on and still get a lengthy stretch in 60 minutes flat. The routines are a lot of fun, really great energy here, no clock watching at all. I was in serious danger of doing this too much when I first go it and burning out - had to take a break.
If I were to recommend one for you to get, it would probably be Stepletic - the fact that it is two workouts alone means it is a great deal for the money. They are both fun - one has more complex choreo than the other, so you can choose to fit that day's mood. If I were to recommend two, I would say then also get #3. This one just always puts me in a good mood.
Good luck shopping!
