Most effective ways to strengthen the wrist??

[IrishSheep]

Wrist is kind of non descript, if you want grip strength then like Dan said Towel Pull ups are fantastic.
You also have static hold such as hanging weighted from a bar or holding barbell/dumbells.

Then you have the forearm pulling type exercises like forearm curls.
Also Zottman curls are very good.

Also There was a wresler training with us a few months ago with incrediable grip strenght, the exercise he used was to take an olympic bar (20.4kg) and make a figure of 8 with it. (like paddling a kyack) until he couldn't hold it anymore.
I'v yet to try this myself but it sounds good.

Thanks for towel pull-up suggestion Dan. Going to incorporate that into my routine. That figure 8 with an olympic bar sounds very intrigueing as well. Let me know how you get on with it if you try it.

Irishsheep thanks for your ideas as well.

Shakeweight?

[LeeCunningham]

Rope climbing or rope rows with 3" rope works great for the grip, as well as plunging your hands into a bucket of rice and then opening/closing your fists.

Cheers Esham but I wasn't convined by the reviews of that product. Thanks anyway.

LOL shakeweight is not really for me I think!

The rope climbing idea is something cool. Might think about setting up something to climb it.

Thanks again everyone for your ideas.
