Deadlift Form & Safety Guide

Proper Form Guidelines

Setup Position
  • • Stand with feet hip-width apart, bar over mid-foot
  • • Hinge at hips, keep chest up and back straight
  • • Grip bar just outside your legs
  • • Set shoulders back and down
Movement Pattern
  • • Push through your feet, not pull with your back
  • • Keep bar close to your legs throughout
  • • Stand up straight, don't lean back
  • • Control the descent back to the floor
Breathing & Bracing
  • • Take deep breath and brace core before lift
  • • Hold breath during the pull
  • • Exhale at the top of the movement
  • • Maintain core tension throughout

Safety Considerations

⚠️ Critical Safety Rules

Progression Tips
