Don't have a target weight in mind for GROWING/developing your muscles. Lighter weight and higher reps will give you mass, obviously as time goes on you can progress in weight as well.
always tought 15 reps low weight was to gain muscle endurance
when i lift i sometime go until failure specialy on last set
sometimes i wanna reach 10 but i get to like 8
