Authors Update: It’s been a year since I filmed this video. My respect for the plate curl as one of the best arm exercises has only increased.
Update #2: My video vanished from Youtube. I must have accidentally deleted it. I’ll put another one in from another lifter in the post below:
Many feats of strength require enormous wrist strength. Your wrist must be able to move with great force through it’s entire range of motion, and also be capable of holding a rigid position against great resistance. For example, you can’t tear a deck of cards in half without being able to hold your wrists locked into position while your hands twist the deck. If your wrists lose tension during the tear, you won’t be able to create the shearing force necessary to halve the deck.
I’m a kettlebell nut, as you know, and while most kettlebell work will improve wrist strength, some focused, intense plate curls will make you stronger still (and improve your grip for more kettlebell work at the same time).
Here’s Adam T. Glass performing the plate curl with a whopping 45 lb plate!
