Elbow Flexor Stretch

  • Beginner
  • Isolation
  • Timed hold
  • Shoulders
  • Upper arms

This unilateral stretch targets the biceps brachii and brachialis by extending the elbow and rotating the torso away from a fixed point. It is highly effective for improving elbow extension range of motion and relieving tension in the upper arms and chest.

Muscles worked

Primary

  • Biceps

  • Deltoids
  • Rotator cuff

Equipment

  • Body weight

Setup

  1. Stand perpendicular to a wall or sturdy vertical post with your feet shoulder-width apart.
  2. Extend your target arm and place your palm flat against the wall at shoulder height.
  3. Position your hand so the thumb is pointing upward or slightly backward.
  4. Keep your shoulder down and back, avoiding any shrugging toward the ear.

How to do it

  1. Slowly rotate your torso and hips away from the wall while keeping your arm fixed and elbow fully extended.
  2. Exhale as you rotate to deepen the stretch, stopping when you feel a mild pull through the front of the arm.
  3. Hold the position for 20-30 seconds while maintaining deep, diaphragmatic breathing.
  4. Slowly rotate back to the starting position and repeat on the opposite side.

Form checklist

  • Ensure the elbow remains locked straight to maximize the stretch on the flexor muscles.
  • Keep the palm and fingers in full contact with the wall throughout the movement.
  • Maintain an upright posture and avoid leaning forward or arching the lower back.
  • Rotate the entire torso as a single unit rather than just turning the head.

Pro tips

  • To target different heads of the biceps, experiment with placing your hand slightly above or below shoulder height.
  • Focus on the mind-muscle connection by imagining your bicep lengthening from the shoulder all the way to the inner elbow.

Make it harder

  • Rotate your hand on the wall so the thumb points downward to increase the stretch on the distal biceps tendon.
  • Gently lean your body weight forward slightly while rotated to add a chest and anterior deltoid stretch component.
