My upper body is pretty unbalanced, because I've been lazy about practicing things on my left side, so naturally it's a bit weaker. So I go to the gym and lift weights to try and balance that out a bit.
I love doing circuit training, I personally find it a really efficient way of working out at the gym, and like jivete mentioned, I prefer to do compound exercises rather than isolation. My typical week is pole - power circuit - yoga - power circuit - chest and back - legs - shoulders and arms
and then on the "non-pole days" I really try to fit in some pole practice where I can because I have a performance coming up.
I worked out what exercises to do by looking around different fitness and bodybuilding blogs. Also, most gyms will have instructors who are moer than happy to help you out and put together a workout plan
Depending on what day it is, the exercises I do are: clean and press (barbell), hanging knee raises, weighted step ups, pull-ups, incline dumbbell press, incline pec flys, bench press, squats, deadlifts, hamstring curls, weighted lunges, weighted side lunges, dumbbell shoulder press, lateral raises, and then i do a bunch of different cable exercises too :)
