Why might I use wrist wraps?
You use wrists wraps when your wrists are in compression, i.e., when you’re pushing on something - not when you’re pulling on something. A wrap gives support to your wrist by acting as an external skeleton for your wrist - you can think of it as a cast or a lifting belt for your wrist. Since the wrap is wrapped around your wrist, it lends support to your wrist and makes it very difficult for the wrist to be in positions of extreme extension (i.e., positions where you wrist is bent very far backward). Lifts that benefit from wrists wraps include all the pressing movements (press, bench press, close grip bench, etc.), snatches, jerks, cleans (this is a gray area as you need your wrists to be in extension to rack a clean), and the squat for those who wrap their thumbs around the bar and have their wrists in extension. Even if you don’t normally use a wrist wrap, it’s probably a good idea to use one if you are dealing with and training through a wrist injury.
