Legs workout

I had changed my workout from the last time I posted, but I got bored with it quickly. I got my new issue of Oxygen magazine in few weeks ago and decided to give their legs workout a try for the next 8 weeks. It's a twice a week leg workout. They gave a sample workout series for the week and I'm trying to follow that. I just finished my third week and it's been a great workout! I'm doing 3 sets of each exercise. Here's the breakdown:
