Finally got around to doing this workout yesterday. I'll preface this by saying I'm someone who doesn't care for barre work in general. Part of it is probably because I need to work on my muscle endurance.
Yes, my legs were burning during the barre exercises - most especially the set of plies and lunges towards the beginning of the workout.
As other mentioned, this wasn't cardio intensive at all. Not sure how "boot camp-y" this really was.
The weighted exercises kind of felt out of place - like, if I'm going to do some cross-back lunges, I want them to feel worth my time - and that means using something much heavier - or, to stay in line with the workout being muscle endurance, then there should have been a lot more reps thrown in with those.
The band work where you held it in place at your shoulder did feel effective.
And while I was a bit apprehensive of the core exercise with the ball where you rolled it down your leg while doing leg drops (I was worried the ball would be a total pain in the butt by falling constantly) - I'll say having the ball there kind of served as an interesting distraction from the core work. I was so focused the whole time on not losing the ball that I barely felt the core work going on.
When doing my own rotations, I'm honestly not sure how often I'll be pulling out this workout.
