It seems that your audio is balanced to the Left channel. My headphones only have your audio coming from the left speaker. What recording software are you using?

You have a sing-songy tone going on with your inflections, causing that same sorta pattern throughout the read. Try changing up the inflections by ending some sentences upwards and others downwards just to give some variety. You can also think about emphasis, volume, emotion, etc to really give more into the character and how you want the audience to react. Your voice was nice and clear which is great, just work on projecting your voice a bit more to fit the scenario of the gym. As in the comments, remember to always triple check your audio before submitting, especially for any auditions you do just so you avoid any mistakes with audio quality or performance! Great work!
