There are lots of different DVD workouts you can try at home. What to do is modify the exercises so that you aren't bouncing around. Instead of jumping jacks, march in place with high knees or maybe do a modified jack. Try your local library for DVDs. your library is not only a great resource for books, you can also borrow DVDs. Look for Zumba or one of the Latin dance type workouts. Those generally don't have a person bouncing up and down too much.
Borrowing DVDs from the library is a great way to save money as well as try different workouts.
Do you like to dance ? How about belly dancing ? That's a great workout You could even try one of the kick boxing DVDs like Tae Bo. just modify the jumping jacks so that you aren't bouncing.
Depending on your fitness level, you could try Leslie Sasone's Walk Away the Pounds or even one of Richard Simmon's DVDs. He always shows options for different levels.
