Has she done any sort of weight training before? If so, how long has she been at it for? If she's just starting out,you may want to start her out on a circuit style program two to three times a week. Circuit style programs are when you do a full body workout two to three times a week. Here's an example of a circuit style program.
Leg Press Machine - Repetitions: 12-15 reps
T-Bar Row(wide) or Lat. Machine Pulldowns(wide grip/to the front) - Repetitions: 12-15 reps
Incline Dumbbell Press or Incline Dumbbell Flyes - Repetitions: 12-15 reps
Straight Bar Curls or Incline Dumbbell Curls - Repetitions: 12-15 reps
Headcrushers(dmb) or Pressdowns - Repetitions: 12-15 reps
Seated Dumbbell Press or Side Dumbbell Laterals - Repetitions: 12-15 reps
Seated Calf Raises or Standing Calf Raises - Repetitions: 12-15 reps
Lower Back Extensions - Repetitions: 12-15 reps
Reverse Ball Crunches - Repetitions: 12-15 reps
A circuit program is going from one bodypart to the next without any rest in between exercises. Once you complete an entire circuit, you repeat it again. If she is just starting out, you may choose to start out doing only one full circuit per workout.
That's just an idea for her. There are tons of different programs you can do. Hope that helps.
