Forearm Pronation & Supination
Pronation and supination — the motions of turning your palm down and up — happen at the radioulnar joints of the forearm. Training these ranges keeps the elbow healthy, supports grip strength, and is essential for anyone who does front rack work, pull-ups, or repetitive manual tasks.
Setup
- Sit or stand with one arm at your side, elbow bent to 90 degrees. Your forearm should be parallel to the floor with your thumb pointing up (neutral position).
- Slowly rotate your forearm so your palm faces the floor (pronation). Pause briefly.
- Slowly rotate your forearm so your palm faces the ceiling (supination). Pause briefly.
- Alternate between the two positions with control. Keep your elbow pinned to your side throughout.
Coaching Cues
What to feel:
- The rotation happening in the forearm, not the shoulder or wrist
- A gentle stretch at the end of each range, especially supination
Common mistakes:
- Letting the elbow drift away from the body — this recruits shoulder rotation instead of forearm rotation
- Moving the wrist (flexing/extending) rather than purely rotating the forearm
- Rushing through the reps without pausing at end range
Tip
Hold a light hammer or wooden dowel to make the rotation more tangible. The added lever arm helps you feel the true end range of pronation and supination.

Programming

Progressions
- Beginner: Bodyweight only, slow and controlled as described.
- Intermediate: Hold a light hammer or club for added resistance (leverage increases toward the head).
- Advanced: Use a heavier mace or sledgehammer for progressive overload, or perform eccentrically-focused reps (slow on the way down).
