Every time I work out i do two body parts. I have two different workout routines per bodypart. An example could be chest and shoulder: Workout #1 Chest: Flat bench press, dumbell bench press/ dumbell fly superset, pectoral fly machine. Shoulders: Dumbbell press, military press, upright rows, lateral raises.
Workout #2 Incline press, incline dumbell press, decline press, decline dumbell press.
Shoulders: Dumbell raises, behind head bar press, bent over laterals, dumbell press.
I dont always do my shoulder exercises in that order, but the chest section is in the order i do it. The next chest workout i do, i will try some new cable exercises i learned, to add more variety because i am getting more and more used to my current routine.
As for experience, i have only been doing consistent and dedicated work for five months. I am making progress, but I believe I might have hit my plateau, so im trying new things.
I also have trouble working out certain areas, such as biceps and shoulders. My workouts always suck on those. I cant find the right weight or the right way to organize my sets for biceps, and shoulders are just hard to fight through the pain. Everything else is coming along better though.
