ElectraStim EM32-E Power Unit and ElectraPads Electrosex Kit use

Hi I was wondering could this be used just like a slender tone device? My job involves sitting down all day aso my stomach muscles are rarely used. I'd love to do crunches or sit ups but my back won't allow it. If it could be used in the same way then I could have dual uses for it and use it for sex as well.
