I tend to focus on my legs since they are such a huge part of the body and I am pear shaped. I do three sets of each exercise, 2 minute rest between each set. Try to do enough weight where you are tired for last two reps and the goal is 6-8 reps per set. I usually choose 3-4 exercises per day. It takes some trial and error at first to figure out what weight to start at, there were a few times I picked a weight that was too heavy and had to exchange it lol. I also had a lot of water weight at first and would do 20 minutes of cardio with a sweat band and then go to weights. Just listen to your body, you want to push yourself but not over do it, try to pay attention to any throbbing or sharp pain while doing the exercise but normal for your muscles to feel tired and sore.
Sun-Quad day: squats, leg press, lunges, leg extensions, split squats.
Mon-Glute day: Glute bridges, goblet squats, glute kickbacks
Wed-Hamstring day: deadlifts, stiff-legged deadlifts, leg curls, kettle bell single legged deadlifts.
Fri-Back day: rows, lat pull downs, iso-lateral(machine) rows, assisted pull ups, one arm rows.

I would look at bodybuilding.com to make sure I had the right form and doing the exercise correctly. Good luck!!

I do heavy weightlifting! I tried cardio as well, didn't work for me at all, even with a sweat band. With PCOS, some of us have elevated testosterone and I read to take advantage of it through weights. Of course, it is nothing compared to males so no worries in gaining crazy muscle. I did bodybuilding.com, I followed some of Jamie Eason's weight lifting plans until I went down to 130lbs and then my husband, who is a personal trainer, took over since it is harder to lose the less you weigh. I can send some of his/my workout plans if you are ever interested.

I would love to see your workout plans! And i will look into the bodybuilding.com as well! Thank you.
