YOGA - I'd die without these videos. I have every single video in her collection and use them all. Easy to do at home, easy to travel with, and they cover everything from relaxed stretches/toning, power yoga/cardio, and even brain rejuvenating meditation.
Don't worry if you can't do all the poses from the start. After 2 decades, I still can't balance my body at an angle on my hands (crow pose). When she gets to that part, I do either push-ups or crunches and then join her when she moves to next pose. Don't stress, just modify all you need. In the beginning, you might not even modify, you might simply watch and sit out that minute. That's fine. Anything goes. My 5 favorites from her below. If you want a total body workout, I suggest you get the Core/Upper and Core/Lower. Between those two programs, you'll get total body toning.
If you're new to yoga, take it slow. It took me an entire month to ever get through a 20 minute routine. Progress a few minutes at a time and it's helpful to sometimes turn the DVD off and practice a pose over and over until you're comfortable with it. No pressure, ok?
