I was going to try and defend doing the big 3 but realize I don’t do them as much as I thought. I do this each week. Main reason I do them (except squat) is because its what 5/3/1 uses and its really the big 4 in that program.
Bench one day, closegrip bench another
Deadlift one then Sumo or RDL the other
Overhead press one day
Front Squat one day and SSB another
Doing 5/3/1 so 2 of the big 3 lifts are my main lifts of the day. As someone who does not compete in powerlifting I don’t see any reason to not bench press, I still overhead press as a main lift with the same priority as bench has. No reason to not deadlift, I don’t have a trap bar and doing deficit or rack pulls seems arbitrary, might as well just do regular DL.
Also if you workout at home or have limited equipment the big 3 are easy. Your favorite chest exercise is the hammer strength flat press machine? What if your forced to go to another gym for whatever reason and can never do that anymore? This won’t happen with the big 3 or some of their barbell variations.
