I'm not in shape either I do my best and even though am slower than Adriene I concentrate on my breathing and execution of the moves to get them right. It has taken me 12 months to understand the breathing but I use it every day now as I suffer from panic attacks. I do it every day and I absolutely love it even though some excercises leave me knackered.
I have one of those A5 spiral bound note books that have dividers in them, mine cost me £1 from the pound shop. I have divided it into 3 sections - gentle excercise, sweaty and one for exercises targeting specific muscles. I date the exercise then chose a category and write my thoughts on it and how I physically felt. It is also a good idea to have an index as once you get going and trying different exercises you look forward to what you are going to do the morrow.
I wish you happy yoga just jump in with the rest of us.

I am rajkumar from India(Tamilnadu). I am 40 lbs over weight. i want to reduce my weight especially my tummy. Which one i do to reduce my belly fat. Whether your 30 days of yoga or is there any separate video there to guide me.
Any help really appreciated. Eagerly waiting for your reply.
