working your deadlits double overhand without a hook grip is one of the best ways to do it just like doing timed farmers' holds or farmers' walks!
my grip strength went from struggling with 495 to 565 wednesday thanks to training this way. In doing so I've noticed EVERYTHING has gotten easier to hold onto.
The slightest changes and incorporations into ones' training can lead to huge dividends. Think about it!
video soon too! I'm not sure what everyone here has or can do double overhand but without a hook grip the biggest pull i've ever heard of is 600 by wade gillingham.
