Thumbs Day

When all of your friends are talking about if they’re going to do a legs day or a chest day at the gym, and you tell them you’re just going to play Xbox all day.

Nah I’m not going to the gym, it’s a thumbs day for me. I’ve been light on cardio also so I might walk to the microwave soon.
