well for me personally............i'm 20, 5'4 at 115lbs........
ok...........well you said her main goal is to lose some extra pounds.......you said she does 30 minutes of cardio............in my opinion, 30 minutes of cardio will only maintain your weight............to see change she needs to be doing 45 minutes - hour....................i know it is time consuming but i do an hour every time i do cardio.......i dont feel its worth it if i do not...........mainly either running or on the stepper...........elipitcal isnt my favortie machine for weight lost.............
and with weights......main rule...i mean if shes getting thur 15 reps no problem.........she needs to increase the weight.....she should be stuggling thur her last 3-5 reps........
hope this helps a little
