Common Barbell Types and Weights

  • Men's Olympic Bar — 20 kg (44 lbs), 2.2 m long, 28 mm shaft diameter. Standard in most gyms.
  • Women's Olympic Bar — 15 kg (33 lbs), 2.01 m long, 25 mm shaft diameter. Used in women's Olympic weightlifting.
  • Training Bar — 10 kg (22 lbs). Shorter and lighter, for beginners or warm-ups.
  • EZ Curl Bar — 6-10 kg (13-22 lbs). Angled grip for bicep curls and tricep extensions.
  • Trap / Hex Bar — 20-27 kg (44-60 lbs). Hexagonal shape for deadlifts and shrugs.

Tips for Loading Plates Safely

  • Always use barbell clips (collars) to prevent plates from sliding off during the lift.
  • Load plates evenly on both sides. Never load one side significantly heavier than the other — an unbalanced bar can tip and cause serious injury.
  • Place the heaviest plates closest to the collar and lighter plates on the outside for stability.
  • When stripping weight between sets, remove plates from both sides alternately to keep the bar balanced.
