my hypertropy (muscle mass) workout looks like this:
-Day 1: Chest and Legs (bench press, dumbbell flies, decline
bench press, back squats, forward lunges, side lunges, calf
-Day 2: Biceps and Abs (barbell curls, dumbbell curls, hammer
curls, weighted situps, V-ups and ended with a plank)
-Day 3: Back and Shoulders (deadlifts, lat pulldowns, dumbbell
reverse flies, dumbbell lateral raises, dumbbell front raises,
military press)
-Day 4: Triceps and Abs (weighted tricep dips, triceps
extension, triceps push-ups, weighted situps, V-ups)
-Day 5: Forearms and Traps (wrist curls, reverse wrist curls, shrugs, rotating shrugs - forward then backward)

3-4 sets/exercise, do 8-10 reps with a weight with that you can do only 9 reps.
Also nutrition is 50% of mass building, not just lifting and pulling weights.
The harder you train, the harder it is to surrender.
