I've decided to take a few days off from training. Seems like I have all the classic symptoms of overtraining. Irritable (okay, I'm irritable most times but I'm more irritable than usual lately), tired, not looking forward to training. I have trouble sleeping.
I did 2 reps of front squats today and didn't feel like continuing with the workout. Something's definitely wrong. I'm not sick though. I can safely say I've recovered fully.
I'll just lay off the weights for a few days.
