I hate you...

Another challenge and trick question(?) from SM I see. He's testing us, I do believe.

All forms of overhead presses (BB, DB or cable) involve the traps. When, on the way overhead, the elbows reach a little below shoulder level, that is when the traps come into play strongly. Traps come into play with most pulling exercise, almost from the very start. Haider makes a good point about elbows. The elbows can be very important in most exercises and where you may want the main focus of an exercise; traps, chest, delts, etc.

   The traps are one of the main stable forces of the upper body. Any extension exercise (out and away from the body) like lateral, front and rear raises hit the traps also.  So, in a lot of ways, your SOL when trying not to involve the important short range and very powerful traps. Even benching comes into trap play. Squats have the traps as a main player.

Here are some suggestions, for what they may or may not be worth. But in any event, the traps will not be taken completely  out of these movements. But than again, why would you want to?

 For the lat's/back you might try pullovers (straight or bent arm), an exceptional stretch and lat mass builder.Can work up to some very impressive weight with the bent arm version, either BB or DB.

With delts try lying side raises, but from a different angle. Lay on your side and have a DB, on the floor, by the upper legs. Now raise the DB up directly  overhead and lower it behind the body. Raise it up back overhead and lower it to the front original position.That's considered one rep.   Use the floor/mat/bench or a incline bench but an incline bench may offer better tension on the delts through the whole lift. Switch it up now and than. Can also do front incline raises.

Sure there are other ways to limit the traps, lot of good ideas of GB. Experience is a good teacher. I'm kind of tapped out myself on much more than what had been suggested. But no matter, taking the traps out of any exercise may be near impossible. Gironda tried, but with limited success. Good Luck.

they do, so do upright rows, and to a lesser extent all of those exercises.

behind the neck press, military press, barbell upright rows, barbell rows, deadlifts, pulldowns/pullups, pullovers

Anyone might try BB Hack Squats with the heels raised (2X4, pair of 45's, etc under the heels), to focus on the quads rather that the hips/glutes. One of my favorite leg movements. Think of it as a form of reverse Dl'ing and somewhat a whole body exercise. Front squats may also be improved by having the heels raise, for a better focus on that teardrop affect. Some find front squats much easier on the lower back than regular squats ever were. Good Luck.

Oh brother what excuses not to squat will we come up with next

Straps.
