I am from the old school of basics when it comes to bodybuilding. I have been training since my teens in the mid sixties always using heavy weights and basic exercises.
My system has always been Press Behind Neck, Squats, Bench Press, Rowing and barbell curls. I perform eight sets of five reps for all exercises and my workouts take about 3 hours.
I do have some fair size but I do not really look impressive. Any suggestions?
For someone who has been training for around twenty years you better have gotten something from your training. Your routine stinks! And the worst thing is that you take three hours to do it. Limited routines such as yours are OK for short periods but to do the same basics for twenty years!!! Where have you been?
Get more variety in your training and increase the reps to 8-10. I suggest you split a routine based on working each muscle group with three different exercises at least, maybe four.
If you want shape and impressiveness then I suggest you use specific isolation exercises. Kill your love affair with the basics. After twenty years it’s about time.
