30 min of dancing - total time was 40+ but actual exercise was 30. Tonight there were issues with my wireless connection - Pandora kept stopping - and then shooting to the next song - I did the best I could which involved some basic exercises while I waited inbetween. My cat has decided its good fun to come over by mom while she is dancing - he rolls around, bats at my feet and plays with his toys around me. It's good for both of us! This isn't my cat but this is what he was doing....
