Is it important to vary the exercises a lot?
Today I just did 4 sets of bench + 2 sets of dumbell incline for chest.
Tomorrow I'll probably do chins, wide grip chins and dumbell rows (no machines, train at home, and cant seem to do barbell rows without pain)
Is it bad if I only got 3 reps in my first set? I dropped the weight accordingly, but counted the set. My chest doesn't feel sore or anything after today, hope 1 week isn't too long to leave it, seems like a long time for so few reps.
