I usually practice on weekday mornings. The classes are full, but not to the brim. The students are regulars, but the skill levels vary. Some people are old, some students are young, but most are somewhere in the middle, like me. The teachers are challenging, but caring, the rooms are hot, but not too hot, and it is all good.
Recently, I have started to practice on the weekends too. My husband has finally succumbed to my Bikram Yoga fever, and since he can only practice on the weekends, I have been going along for moral support. But class has been extremely challenging — because of the heat. So challenging, that we leave class spent, and exhausted, and this can last through the rest of the weekend. Clearly not the goal we were seeking.
