Sometimes, one needs an unbreakable oath to start a change in one's life

By Excellent Apollon and Swift-footed Hermes, Gods of the Gymnasium, I swear this oath, on the 3rd day in the 9th month of the Gregorian calendar, 17th in the month of Metageitnion:

• To pursue P90X to glorious victory
• To preserve this oath in honour and care

Under the promise of priceless reward at its accomplishment, yet under pain of punishment in reckless failure, unless released for reasons judged necessary and dire, may it be so.

By Unerring Apollon and Unfailing Hermes, and by the human body in its magnificence, for the next 90 days, it shall be so.

Update: 16.9.2012
Programme on hold until modified appropriately for skinny, underweight dedicant. Oath paid with seven days of sacrifice.

Update: 15.11.2012
Oath fully paid. Programme slightly modified for lanky, energetic lads who travel 4 hours a day, sleep 7.5 hours of daylight, and are conditional pesceterians. Sort of. New oath is as follows:

By Excellent Apollon and Swift-footed Hermes, Gods of the Gymnasium, I swear this oath, on the 15th day of November, 1st in the month of Maimakterion:

• To pursue the well-being of my body and mind in the best way known to modern science, to the best of my capacity

By Unerring Apollon and Unfailing Hermes, and by the human body in its magnificence, until the day I change form, it shall be so.

Now wasn't that a lot easier?
