The forearm muscles lie between the elbow and wrist. The forearm is composed of 3 major muscle groups:

• Brachioradialis
  Responsible for flexing the forearm at the elbow.
• Flexors & Extensors
  Used in Gripping, and flexion/extension of the digits (fingers).

Functionally, the forearms are important in many gripping activities. They may be trained through isolation, or as part of compound movements such as Deadlifts and Chin-ups.
