I have to say "Sit and Stands." I call them "Sit and swears", because instead of counting, "five, six, seven,.." while I hold the position, I say single syllable swears until I stand. This helps a bit. And yesterday during the low end plie squats on LL, I thought that I was going to fly away because my legs were flappin' like a pair of wings. But I love how sore I am today!
