A few days ago, I embarked on my yoga studio's challenge--30 classes in 30 days and you get 30% off the next month's card. It will be difficult, maybe impossible, to complete given my teaching schedule and the fact that the times I'm free don't necessarily coincide with any classes being offered. So far, I've completed three classes--yoga, pilates and gentle yoga (basically lying down on the floor doing next to nothing). I've only done pilates twice and each time I've felt it in my abs for days (I currently ache from Friday night). But that's good as my core is a weak point and my waistline vastly expanded since Christmas, along with my appetite. Plans are for two classes tomorrow morning and maybe a third tomorrow night. The studio isn't open Tuesday so I better get my classes in while I can, especially as this will be the last week before classes resume.
