So it has been over 24 hours since yesterday's workout, I did my upper body I worked on every upper body muscle and did at least 4 sets of 8 to 10 reps of each exercise. A few were; dumbbell bench press, isolated bicep curl, standing bicep curls, scullcrushers, shoulder press, and some standing shrugs. Now all my muscle are a bit itchy and I was wondering if I was overtraining or if this is just something completely normal and I'm making a big deal out of nothing?
