I found this online, looks helpful!

From the link, a shaded gray box will appear in the middle with different scrolling information. When it scrolls "routine generator", a green box will appear. Click on it. On the right side are boxes for you to pick different types of workout you'd like.....and it'll spit out a routine for you. I'll try mine tomorrow! Hoping all the ones that it picks for me are unlocked......
