  3. Keep palms facing up and top of dumbbell vertical throughout.
  4. Squeeze biceps at top and hold briefly.
  5. Lower dumbbell slowly back to start.
  6. Maintain tension in biceps without locking elbows.

Coaching Tips

Form Cues

  • Elbows pinned to sides
  • Palms face up always
  • Squeeze at top
  • Control the descent
  • No swinging

Breathing

Inhale as you lower the dumbbell; exhale as you curl it up while bracing your core.

Tempo

3-1-1

Range of Motion

From full arm extension with elbows slightly bent to dumbbell reaching chest height, keeping wrists supinated.

Safety

Safety Notes

  • Start with light weight to master grip
  • Avoid if acute elbow or wrist pain
  • Keep core engaged to support posture
  • Do not swing or use leg drive

Spotting

Not typically needed due to isolation nature; use lighter weight if form breaks.

Common Mistakes

  • Using momentum from body
  • Allowing elbows to flare
  • Dropping the weight quickly
  • Overextending elbows at bottom
  • Poor wrist alignment causing strain

When to Avoid

  • Acute elbow tendonitis
  • Wrist injuries
  • Shoulder instability

Flexibility Needed

  • Wrist extension for grip
  • Shoulder flexion overhead if advanced

Build Up First

  • Basic bicep curl form
  • Stable standing posture
