We've done the speed 4 times now and I'm still struggling with breathing when I do it. Is smaller steps easier? (This is sort if what I've been doing) or does it make no odds? I'm not keeping up on the 150bpm - have to slow down to be rested enough for the fast one. And the 155bpm "warm up" nearly kills me! Anyone got any advice for completing?
