The hook is the most common move in arm wrestling. This is because it is the move that is used when armwrestling is preformed in bars and movies. It is an "inside" move, meaning you are trying to beat your opponent's arm instead of his hand. To be successful in a hook, you should be stronger than or at least equal to the strength of your opponent. You don't need to benchpress as much or so because this strength counts very little in armwrestling. Instead, try to measure your forearm and bicep strength against your opponent. If you believe that you are weaker then him or her, try to go for the toproll instead. If, on the other hand, you stronger then your opponent, you can really blast him in an impressive manner with the hook.
HOW IT IS PERFORMED If you have ever arm wrestled across a kitchen table, you have probably already used the hook. To perform the hook, you curl your wrist as hard as you can. Now, get your body over your arm. Keep your arm close to your body. To get the pin, push down with your arm and body.
As a rule it is important to use your body weight to get maximum pressure on your opponants arm. To do this you will need to keep your arm close. Work alot on the technique to lock your arm.
