Now I'm probably going to really confuse you because I LOVE FYC. I just got the workouts last week. I've only done EFM and SIM so far then today FYC and I absolutely loved it. Jury is still out on SIM and EFM. I'll have to wait and see on BBBB, I do that in a couple days. These workouts are difficult if you do the moves right. I really ever get sore but after doing SIM my butt was sore and after doing fyc my core is feeling it. YOu really have to engage your muscles, brace your core and feel the work. NOt every move is going to kill you, just like some of cathe's moves don't kill you. They are advanced workouts tho. They are a completely different type of weight training workout because you are ALWAYS moving, there are very few breaks and you usually work at least two things at one time. It's hard to explain. You really have to focus, don't go too heavy. I mixed up a rotation with cathe/turbo jam/yoga/pullups and the tlt's for the next month. I only added in a couple of cathe weight workouts, so we'll see what happens.
I do wish I had the cleavage problem tho.
