Incase my other two comments about your strength misspelling wasn't enough, it's on "Cardio Training" The Description Says "Manage breath to keep strenght longer".
Found strange bug where when you pick your own numbers and you click one and set it then go back to the main screen (Without Clicking away) you wont be able to roll.
I will do that in v1.03, thanks for your input. [EDIT: 6/21/2015]: Fixed a few hours ago. Forgot to update my reply.
