Thanks for the advice. I'm 18-year-old and I have been doing workouts for more than one year. I usually train chest & triceps on Monday, biceps and forearm on Wednesday and so on. I will allow one day for my body to recover. My arms are not as strong as before and they ache after I do one or two sets.
