The wrist extensors are the group of muscles coursing from the outside of the elbow, along the top of the forearm to the fingertips. These muscles are responsible for extending the wrist. Common with conditions such as ‘Tennis Elbow’ these muscles can become weakened and play a vital in our upper limb function.


  • Position yourself with the affected limb positioned on a bench or as shown below or resting on the knee
  • The elbow should be bent to approximately 90 degrees
  • Hold the weight with the wrist in a flexed position
