Functional training has become very dysfunctional in the last few years. The most functional exercises are the exercises focused on movements applicable to daily life. Squatting on Swiss ball on one leg with someone poking you with a sharp stick in the eye is not functional. Squats, deads, lunges, shoulder presses, chins, trunk rotations, even curls...these are more functional than what is being called functional today. Having said that, there are plenty of people stuck in the 70-80s doing dysfunctional training from back then as well-all bench press all the time, underhand tricep pressdowns, preacher curls, leg extensions and curls constituting a whole leg workout, 1000 rep ab days(which means 1000 rep crunch day), 90 degree leg raises...all equally as dysfunctional.
