Use each one on a different day and you'll feel and see the difference. This series in particular helped keep my 70 pound weight loss in check for the past 8 years

The Third one is the best for weight loss

Surprisingly good, although the music can be distracting

Short workout that makes your whole body sweat

Great for the upper arms

Nice 20 minute flow where you don't stop moving until relaxation pose

These dvds are great if you only have time to do a 100 minute yoga routine once during the week. They can be broken up with little to no warm-up, but try to do the whole dvd particularly the Seane Corn one. You will feel refreshed and a sense of accomplishment afterwards.
