How to load safely

• Always load plates symmetrically — equal weight on both sides every time.
• Slide collars on and fasten them before stepping under or approaching the bar.
• Load the largest plates first, closest to the sleeve collar, then work down to smaller plates.
• When stripping the bar, remove plates from both sides alternately rather than all from one side at once.
• Double-check the total before you lift. A quick mental check takes two seconds.
