I got a great one.....

squats
bulgarian lunges
single leg lying hamstring curl
leg press
db romanian deadlift
standing calf raise
seated calf raise

Super set every 2 except for squats.....take 30 seconds in between each squat for 5 times.

You may want to take out the calf exercises depending on her goals.

here's my current leg program but it's a killer!
Squats 4 sets 15 reps, 12 reps, 10reps and then 8 reps
the next three exercises are tri sets. I don't rest from one to the other.
Leg Press 15 reps, immediately to leg extensions for 15 reps and then finish the set with walking lunges.(around the room) which is about 15 reps.

I do that giant set about 4 times and i'm pretty much dead after it....lol

If I've still got some steam in me..hehehe...I'll finish with some stiff leg deadlifts. I do calves on two other days during the week instead of on leg day.

I would certainly not suggest this program for a beginner though.

Is she a beginner or how long has she been training for?
