* Pinch yourself hard before that final sprint. (I don’t think this will work but causing a bit of pain might give you a quick adrenaline rush) Only use this for the sprint, apparently extreme amounts of pain prior to competing in other events can give boosts because of raised blood pressure from the pain. One pinch can’t hurt tho right? And I’m not sure how high BP will help anyway.
All the suggestions are starred:
*** 3 stars. IMHO it will work
** 2 stars. It might work
* 1 star. Can’t hurt
X 1 cross. It CAN hurt if done wrong.
