The hand-wrap’s purpose is to protect one of the kick-boxer’s most important weapons, his hands! The hands are made up of many small joints and small bones that could easily fracture from the impact of repeated punches. Hand-wraps are there to hold your hand together providing support for your wrists, fingers, knuckles, and the entire hand itself.
Many people incorrectly think hand-wraps are for extra cushion or protection for your knuckles.
The hand-wrap purpose is NOT to cushion the impact; that’s what the boxing gloves are for.
The hand-wraps are there to secure all your loose joints and moveable bones. The hand-wrap fastens all your joints together so the shock is better distributed across your entire hand. You don’t want your joints to be moving freely and independently when the hand strikes an object. You can suffer a fracture if joints are moving in their own direction.
