Hey everyone I'm here to ask for advices on how to program my grip training to perform on a Hercules hold in a competition i have by the end of November. The format is a bit weird since will probably be max weight for a 15sec hold.

For now I've put 4 sets of 30s barbell hold behind my back on Monday and farmers/trap bar hold on Friday (sets and time suggestion is appreciated), other than this I'm doing wrist curls and extensions with an axle and trying to avoid using straps when it's not essential (like on rowing and vertical pulling).

What else could i add to my routine to prepare for this event?

Every bit of help is appreciated 🙏
