It's goes without saying that it's easier to walk forward when you're standing up. It's harder to walk forward when you're lying down. Yeah, your feet is doing the walking motions, but you're either lying down on your back or lying on your stomach (Unless you're lying down on your side) while your feet is doing the walking motions. Not much progress is expected. However, when you're standing up and your feet is doing the walking motion, then it's easier to walk forward. However, you don't need to do any walking if you're tired. And if you're tired, then you need to get some rest. It's best to get some rest if you're lying down. Before you lie down though, don't forget to grab yourself a delicious slice of pizza.
And as I'm lost in thought as I enjoy a delicious slice of pizza, here are some photos of Laura Marano.
