I was taught the Squat, BB row and BP were the Big Three. To be done with a 5X5 whole body workout. Either twice or three times a week. Works extremely well, over the years, for may be thousands of guy's. Quite a few athletes use this program for getting stronger and gaining muscular weight.
The Big 4, offered by Slin1, is also very good. Though there is no direct pulling exercise with the arms, like rows, hi-pulls, cleans, etc. Would need than for more of a well rounded program.
The two Olympic lifts are exceptional also for a short and getting to the point workout. In any event, most all compounds are king for power and muscle mass . As a BB'er you could use only those above 3 or 4 exercises for outstanding results. With a higher rep BB'ing range of 8 to 12. All build a great foundation for strength and size. In working out, just remember K.I.S.S.. Good Luck.
