I was in the room before class just relaxing and calming down in preparation for the class. On a whim, I tried to touch my toes. I expected to just get to my ankles again, but I pushed a bit and barely took a swipe at my toes. By the time we got to the Paschimottanasana near the end, I was grabbing my two big toes and I could just lock out my knees. It was a struggle, but my knees did lock out. =D
It took 18 classes to get to this point. And I only go twice a week, so that makes it 2½ months.
They actually recommend that for the first month, you do at least one class every day and then at least 3 times a week thereafter for maintenance. But I could only do 3 times a week, max... Tuesdays, Thursdays, then either Saturday or Sunday, depending on what my weekend looks like.
One of the things that I love about Bikram Yoga is that you hear so many amazing stories of fellow practitioners in the classes. People who were told by their doctors that they'd never walk quite right again, never be able to do this or can't do that because of some physical ailment... have either gotten their bodies back into some semblance of shape or are seeing amazing improvement.
