Hook grip vs. straps...

So what are the facts, does the use of lifting straps prevent increases in grip strength?
My deadlift starts to slip from my hands when the weight is in the high 200’s, so I’ve been using hook grip.

In this video from Calgary Barbell, he advises to train with straps right up until your top singles, then use the hook grip. Since Bryce is a world class powerlifter, I think I’m going to try this method for a while.

Does anybody else have thoughts, experience training with straps?

I use hook grip on my comp singles and probably one set of back off work. Then straps.
I use straps on all supplemental lifts, except maybe supplemental deadlifts close to a meet. Then it depends on how my thumbs are doing.

I’ve not dropped a deadlift yet and my best pull in a comp is 230kg (507 ish lbs)

Isometrics, generally, are pretty lousy for inducing hypertrophy and strength gains.

The grip on a deadlift is an isometric.

Deadlifting is a pretty lousy way to develop “gripping muscles”.

I think of the deadlift grip as a sport-specific application (basically isometric endurance).

So, if you want to hypertrophy and strengthen “gripping muscles” I would do so using resistance throughout the range of motion of your grip.

If you want to optimize extant muscle for deadlifting…deadlift heavy singles with hook (or what Dave said).

What’s an example of this?
