I love your articles, Anna Maltby. When you said do burpees, and just walk, I was there!
I specially love this one because you know how to make these GIFs! Wow.
May I request, clothes in colours that contrast and do not match the sofa(couch), please? Your iPhone looked OK on my iPhone 6 otherwise.
Or you could move the sofa away, and use the wall instead. A clear, clean outline of your body against a contrast background.
