work out videos?

What videos have people seen results while using???Is it true that if you sweat more, you burn more calories? Please help..I'm a caregiver and I am stuck in an apartment for 12 hours a day so I have PLENTY of time to do some cardio and strength training. I would just like to know which ones work. If it helps at all I am about 5'3" and 135lbs..I've been doing turbo jam and turbo sculpt for the past two weeks, monday-friday and I havent really seen a huge difference except for feeling like I have more strength in my arms. Help me please!

Hey there, I am an aerobics instructor. Have been for five years now. I noticed that no one was losing weight in my classes unless I incorporated lots of jumping (Instead of marching) we do allot of jogging in place type movements as well as jump roping in place type movements. Kicking up a notch made all the difference for these women and me too. You should see my legs!
