I remember a conversation I had with Michael Boyle last Summer about grip strength. To paraphrase, he was joking about how ridiculous it is for hockey players to spend so much time doing wrist curls when they’re legs are so weak they’ll never get to a puck anyway.
The take home message is that you’re likely to get all the grip strength you need from other exercises. As an example, let’s look at Mike. Although he’s withered away to a measly 205, he’s kept his deadlift around 600 lbs. He’s doing a high rack pull in this video. Think he needs to do wrist curls?
