Re: Deadlifting with a thick bar for grip?
Do you use a mixed grip and chalk?
It is highly doubtful your double over hand grip will catch up to your strapped lift in 3 weeks.
Infact your grip strength would have to be excellent and you deadlift under strength to be able to use just a doh grip.
Majority of powerlifters use a mixed grip. The odd few, like myself use a hook grip.
