If you do nothing else, do yoga.
Yoga is moving with your breath. It is focusing on your breath. Yoga is strength meeting flexibility. It is getting into your body and out of your head.
You can’t be bad at yoga. If you can balance on one elbow it doesn’t make you good at yoga, if you can’t balance on one elbow it doesn’t make you bad at yoga. If you are moving and breathing and if sometimes it feels great and other times it feels hard, then you are doing yoga.
My only aim for you is that you leave feeling better than you did when you came.
