That's funny you say that because I'm taking a beginner yoga class at a junior college and my teacher, a wonderful older South-African woman, always barks "it's not about strength!".. But the way I sweat, my arms and breathing are so shaky and then later how my whole body is so sore after... How can you say it's not about strength!? LOL I understand her sentiment, because she doesn't want excuses and its not JUST about strength.. but c'mon... It's at least part of it !
