I've been working out for about 5 years but really only the last few have been productive and gainful. I have a respectful amount of muscle, about 165lbs of lean mass or more. So I'm not sure if I'm a beginner or intermediate weightlifter because I'm still making progress simply adding weight each week to my rep schemes. I started doing 4 day pull/push, 2x frequency workouts.. I'm curious if a typical linear periodization rep scheme would work better or if I should change reps each week and make it weekly undulating periodization.. doing reps such as 12-15, 6_8, 9_11,etc... Rather than 12-15,8-10,4-6? I know one is better for staying fit among each rep scheme but it makes it hard to progressive overload when you change reps each week too.. any ideas?
