Again, it's just a suggestion. For strengh alone, yes.....one would want to work with low(er) rep ranges as strength is a more a function of CNS recruitment (motor firing, # of motor units recruited, rate coding, etc). 80% for most people is ~8, and in all actuality one would want to be training above 90% for strength gains, but that is a moot point for the time being.
If your girlfriend has a posture problem, than I would highly suggest she get someone to assess it. For the most part, I can almost guarantee she needs more scapular work, more glute activation work, more core work, etc. Posture issues usually transpire from horrible program design and everyday life in general. Meaning, yes you CAN fix postural problems in the gym, but that is only one hour of "fixing." There are still 23 more hours in the day to mess it up. Alot of issues with posture deal with breaking motor patterns that promote horrible posture (ie: slouching at the computer, hunched shoulders when walking, sleeping the wrong way, not maintaining a neutral spine when training.....amongst others). It does no good to fix it, if she is doing other things throughout the day that perturbes poor motor patterns, know what I mean?
