Query: Don't use if you are recovering from injury

This dvd was not meant for those just starting to get into shape or trying to get back in shape after recovering from something like knee injuries. On the modified movements, you really cannot see them very well. If you are confined to a chair, you cannot do a lot of the exercises. After trying this video once, you may be want to give up. Not very inspiring if you cannot do the standing exercises. Read the dvd descriptions carefully if you are seeking seated only exercises. There are other dvds in this series (Chair Aerobics for Everyone) that are completed seated.
