Bikram routine doesn't include downward dog posture.
You'd have to try at least 20 - 30 sessions not spread in time too much to make any kind of attempts at judgement.
First class will feel over intense (I thought I'm going to have heart attack), but it gets better quite quickly and it's great to see your own progress every class.
There is a sweet spot somewhere around 80-90% of your "max I can do" that can keep you through the class without feeling of being in torture chamber. The nob is quite flexible between simply standing or even lying down and doing maximum effort.
