My rule of thumb:
Part Time Training during 1st week of creation. The 6 Sessions are all Cardio in a cheap Pristine/Brand New Gym. Depending on your Supplements and Pops, you may want to continue Part Time for a second Week.
No Training on the day of a Friday or Saturday Fight.
Remember, you can only change your Training Intensity once a week, this resets on Sunday.
So, if you're on No Training the day of a fight, do not switch back until your Energy has been recovered, you'll be receiving the money during your entire recovery.
If you finish the fight early and aren't hit by much Energy loss, just switch back to Full Time Training on Sunday, after 11pm GMT
Good luck!
