7 minute workout

I often workout to music from speakers without headphones where I must maximize my phone speaker volume to hear the prompts. At max volume, the voice narrative isn't quite as loud as I need it but the ding and the whistle are literally deafening. If you could normalize all three sound elements to a similar volume, obviously with the ding and the whistle being a little louder, that would really help improve the quality of the app. Thanks.
