Query: Great Energy Boost

Seems like a lot of the maternity workouts are for women that don't usually move. I know that we aren't supposed to loose weight or work too hard. This video is perfect! Not too much and not too little. You can do an express workout that is perfect if you don't have a ton of energy. They also take time for you to get water which is really important while you are exercising. I don't have an exercise band but I used hand weights and it works just as well.
