This summer I was killing myself working out at least 60 minutes a day, 6 days a week. I thought that I had to do that to lose weight. Then I took two weeks off due to traveling, during which I rested and relaxed a lot, didn't overeat, but didn't eat terribly clean, either, and no exercise. I LOST inches! I looked better after my rest break than before. I came to the conclusion that I had been pushing myself too hard and my body just didn't like it.
So now my goal is to work out 5 days a week, (2 strength, 3 cardio) w/ 2 rest days (one can be active rest like yoga, stretching or maybe pilates.) I work out for no more than 60 minutes, usually more like 45-50, using a lot of the DVD premixes (I've got Hardcore, Body Blast and the Low Impact Step DVDs.) I feel better, am sleeping better, and look better in my clothes. I've stopped weighing myself because it just makes me crazy, I do better when I go by how I look in the mirror and how my clothes fit.
Today I worked out for just less than 40 minutes - did an Imax 3 premix and worked my hardest!
So, long answer to your question, yes, I believe that 30-40 minutes of working out can be enough. Just work hard when you are exercising, eat clean, and get adequate rest. The most important thing, IMO, is to LISTEN to your body.
