Move your butt

Dunno what's gotten into my aerobic instructor. For today's class she moved us through a very fast pace step till I was scared my little heart would give out anytime. Then followed by guerilla like arms and legs exercise, weight added that I started to consider calling hubby to drive me home, just in case I would not be able to move afterwards. To top it all, the aircond and fan was not working and being aerobic room, no window exist either. Gosh.....I was lucky I managed to reach home without hyperventilating and my legs were still attached to my torso. Phew!!!!!!!!!!
