So far, I'm loving Combat! I've done Combat 30 two times, and both times I was sore afterwards. I was surprised, because it didn't seem too fast paced and I was able to do the entire thing, though I was sweating and out of breath at the end. I did Power HIIT 1 today, and I liked it too. But, I was surprised that it had a brief weight section. I expected it to be all cardio. I like the cast and so far the moves have been really fun.
