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

  1. 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).
  2. Slowly rotate your forearm so your palm faces the floor (pronation). Pause briefly.
  3. Slowly rotate your forearm so your palm faces the ceiling (supination). Pause briefly.
  4. 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

Video and animated demos coming soon.

Reps 10-15 per arm
Sets 2-3
Frequency Daily
When to do it Warm-up, desk breaks, elbow/wrist prehab

Progressions

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