Hi everyone - I have been vegan for 25 years. Working out for about 20 years, but only seriously trying to build mass for about a year or two. My questions are about number of exercises to do per body part. I really enjoy working out. When I am doing back, there is probably 9 or more exercises I like to do. My concern is I don't want to overdo it. I want to put on muscle mass, but not planning to compete. Just get bigger. I try to limit my workout to 60 - 90 minutes. My current routine for back: 3 sets bodyweight overhand pull-ups Cable or machine rows Cable or dumbbell reverse flys or rear delt rows (any advice on one over the other?) Bicep curls (cables or barbells or dumbells) Cable pushdowns Close grip neutral pullups Chinups Lat Pull Downs Close Grip Rows On Chest/Tricep/Leg day, I do Bench Press Flys Tricep pushdowns Leg press or squats Leg curls Leg extensions Calf raises On shoulder day, Overhead press Lateral raises Front raises Any suggestions would be appreciated. Thanks!
