These are listed in my opinion not in any order though.
All listed are freeweight motions
1.)Bent over barbell row(curl grip or regular grip)/dumbbell row
2.)Any squat variant
3.)Any deadlift variant
4.)Any benchpress variant(Powerlifting, close grip etc etc)
5.)Military presses
6.)Pull-ups/chin ups with or without added weights(Curl grip or regular grip)
7.)Dips with or without added weights
8.)Shrugs*/upright rows
9.)Skullcrushers*
10.)Dumbbell/barbell Lunges
All the exercises compliment each other.However those marked with * are more of isolations and shouldnt form the bulk of your workout.
Best 3 in my opinion are
1)Squats,2)Dips and 3)pullups.
I honestly know people who only do weighted dips and pullups for their upperbody and they are still very strong.
