So my step dad has some ideas about lifting and he used to lift and he's a pretty big guy (6' 5" 290 lbs in his prime). I'm doing a four day split and he keeps telling me, I'm not working out right, because I won't really gain a lot of muscle mass if I'm benching and deadlifting and curling less than three times a week. He has also always done three sets of ten reps for each exercise. He knows I listen to the guys on the forum and has been bugging me to ask you guys what do you think, even though I already have an idea what you guys are going to say. This is more just to humor him.
