You may not like the sound of this, but the problem is not your wrists, it’s you. Well… maybe not you but the way you are attempting to do said exercises. When people tell me they can’t do plank because it hurts their wrists, I first ask them if they have had an injury or surgery. After they say no, and they usually say no, they’ll continue to tell me that this is also why they can’t do push-ups. Sure.
Somehow, despite what your instructor has advised you to do, you insist on asking your wrists to hold you in a plank, rather than using the giant leg muscles or stabilizing muscles of the core to maintain the position. It is just poor form, yet the truth is, depending on how long you’ve maintained poor form without engaging the appropriate muscles, you may have actually caused damage to your wrists.More
