Check out the bench grip in this PIC

[Liftbig]

good point slobber. staying tight during a big lift will make or break the lift.

that pic is not too shocking. Ive seen people do (and have done) reversing the thumb grip durring crusie week just to change up a little.

More comfortable for me not to wrap my thumb around the bar.

I'm a moron too, no thumb for me and no problems after 13 years. of course, it only takes one time but my theory is that if I "lose" a big bench (big to me) that thumb or no thumb - I'm gonna feel it if my spotter doesn't bail me out.

I bench both ways...
I find using no thumb is A LOT less stress on your wrist as the weight sits closer to the base of your hand and doesnt pull your hand backwords... However i can push more weight with my thumbs wrapped around teh bar....
I guess Im a moron too occasionally!
