30DS--how much worse is Level 3 vs Level 2?
I have been doing 30DS for 3wks now...Mon/Wed/Fri. I have done the 1st 2 levels and my friend and I really struggled with Level 2. We can't even imagine how difficult Level 3 is! All the planks, I could barely keep myself up! :( So tell me the truth, how much harder is it???
