I mean, say I'm working my pecs (or biceps, quads, etc.). How should those muscles feel after a workout? I notice that the muscles I work out are fatigued while at the gym, but after I leave, they feel pretty normal walking out. They aren't sore whatsoever after a few hours and certainly not the next morning. Am I doing something wrong? Should they be more sore? I pretty much do 3-4x8, and by the eighth rep, I can't lift for the life of me. Should I be doing more weight, less weight with more reps? I'm concerned mostly with looking bigger.
