Whew. I haven't had time and won't for a while so posting here which has the least daunting backlog. Cheating, I know....
Last week 4 barre classes and a couple of miles behind the baby stroller. Yesterday barre. For the "Core and More" she does a warmup for 5 min, then launches into a 20-min sequence for one side. Immediately followed, of course, by the same 20 minutes on the other side. You are completely wiped out after the first side, but when you get to the end of the class it was the quickest 45 minutes there ever was!
@DJC3 we do a hand-weight thing we call "swan arms" which is similar in concept to your "flow row", except no rows. Our deltoids are jello after that one
but we haven't even done a plank yet!
