Honestly mate, you're showing all the symptoms of over training. Lack of progress and lack of motivation being the top two. Keep going like this and you'll lose muscle and get fat. I can almost guarantee that after a week you'll be itching to go again and if you start to feel the same again fairly soon you'll need a bit more time off.

You've made great progress in the last few years. Its not going to suddenly disappear after a week off.

Try it and tell me I'm talking out of my arse if it doesn't help 😊
