Help arm wrestling question

[thrasher15]

Have a possible match vs a ex pro arm wrestler in 2-3 weeks. Have never done specific exercises for the sport.
I will keep doing normal workouts and add any additional exercises for this possible match.
As I say don't have long what are the best exercises can I do to help me defeat him?

grip, arms and shoulder internal rotation concentric action, shoulder external rotation eccentric action

i.e. fat bar db holds, hammer curls, cable int rot, heavy cable ext rot

that's some but it all depends where you are now

Also what can we do to minmise the chance of Injury, bare in mind we are both very good and there will be one hell of a force.

win is about all you can do
