It's a good concept, circuit training. It's go-go-go from the beginning so if you're not in great shape then this will be an eye opener. We did 6 sets of 4 reps lasting about 3-4 min each throughout the 1 hr we did.
Liked: TV monitors tracking your heart rate and the trainer was really nice
Don't like: that you're constantly comparing yourself to others, and it can be distracting as you're trying to figure out if you're in the "zone". Which is not really a big dislike......
I had a free class at 6:30am and it was packed on a Saturday morning with just one guy, about 15 people. The gym itself is small and confortable feeling, and orange is the color which is vibrant and inviting. They had a few things for sale but a little expensive.
The program itself I think is too expensive, but I think it can work for people who like to do different things in their workout instead of just sitting at one station the whole time. Good luck.
