I just received this only a few days ago and I'm not in great shape , but this is a tough workout and it does goes very quick. I barely got through each one so far but I am not giving up. I highly recommend this to anyone wanting to get in a quick workout in your own home. I love going to classes but it was getting to crowded for me so I wanted to try this and this is way better then any class I have been to mostly because of the comforts of your own home and it works you hard and fast and then its over. It comes with some cool meal ideas and plans to get you started as well. Give it a shot! you wont be disappointed!!!

If you put this in your wallet in your purse, there is NO WAY you will hear it unless you are in a soundproof booth. Not very useful. Maybe useful to find keys in your house, if your house is 300 sq. ft. and a soundproof booth.
