Over-rated....
Leg Extension machine.
If I had my way, Id ban this machine from gyms.
Because its just plain bad for the knee joint with the shear forces it places on the patella.
Other than that. Basically any exercises which stresses on the dysfunctional movement of the human body.
They hardly translate to increases in real strength where the body needs it for daily or foreseable usage.
Under rated....
Any funtional movements, how the body intended....
Chins ups and bent over dumbbell rows (two handed). Great range of motion for the lats, and hitting the rhomboids and middle back nicely, combined with unilateral training yet nobody ever ever ever ever ever does them.
The only unilateral back exercise I see people do is one armed dumbbell rows kneeling on a bench, which I think is possibly over-rated.
