-Tricep Kick backs of any sort, most people just work calves and rotator cuffs with them...
-BB or DB upright rows , overrated and better rear-delt, trap and scapular activation exercises without the high risk of injury.
-Crunches , should spend more time building the core with other movements rather than just crunches, i.e. Planks (variations) , Oblique work with bands , heavy squats, etc...
-Seated Machine Leg extensions , this is just my opinion but I think it got popular due to the love for it from BBers but I think for mass, and strength development, far better knee extension movements exist i.e. Front Squat, Hack Squat, Lunges, etc...
Hm...just to name a few i guess...
