Bent over rows, deadlifts, chin ups. 3 sets of 5 is not that bad though, so just keep doing pull ups and they will definitely come. Also try doing something like 8 sets of 2 reps but doing the 2 reps completely without any cheating and from a dead hang
Do you want to apply sets to everything you do? When I do push ups for example, I just usually just get down and do a ton at once, rather than separate it over sets. Would it be best to divide even those types of exercises?
