I've been working out steady for about two years. I have always isolated my muscle groups( back day, chest day, etc). I have gained about 25 pounds in the last two years so it has been working but i seem to be at a plateau. So after some research i think im going to try workout that focus on a push and a pull day.

Push day example

Incline Barbell
Standing DB Shoulder Press
Close Grip Bench Press
Seated Calve Raises
1- Leg Box Squat

Pull day

Close Grip Bicep Curls
Chin Ups
Bent Over Overhand Barbell Rows
Seated DB Shrugs
Deadlifts

Now this is only two workouts out of eight i have gathered info on. It will be a split workout switching every week. It will be heavy lifts(75% to 80%) 6 to 8 reps 4 sets.
im trying to increase my strength and put some weight on.

Any info on this type of a workout would be greatly appreciated.
