Key Considerations
- A standard Olympic barbell weighs 20kg (44lbs) — this is your starting weight before adding plates
- Plates are loaded equally on both sides to keep the bar balanced
- Common plate sizes in kg: 1.25, 2.5, 5, 10, 15, 20, 25
- Always use clips/collars to secure plates on the bar
- When unracking, ensure the bar is centred before lifting
Specific Adjustments
First Time
Start with just the bar (20kg). This is a respectable starting weight for many exercises.
Adding Weight
Add the smallest increment possible (2.5kg total = 1.25kg each side). Microplates are valuable for steady progress.
Tips for Best Results
1Learn to quickly calculate: target weight minus bar weight, divided by 2 = weight per side
2Example: 60kg total = (60 - 20) / 2 = 20kg per side
3Load the heaviest plates closest to the collar, lighter plates on the outside
4Always double-check both sides match before lifting
5If the gym has colour-coded plates, learn the colour system (often competition standard)
Frequently Asked Questions
How heavy is the bar without plates?
A standard Olympic barbell weighs 20kg (44lbs). Some gyms have lighter bars (15kg women's bars, 10kg training bars). Check with gym staff if unsure.
What is the minimum weight I can put on a barbell?
The barbell itself (20kg) is the minimum. To go lighter, use dumbbells, kettlebells, or a lighter training bar. Some gyms have 1.25kg fractional plates for small increments.
Do I need clips on the barbell?
Yes, always use clips (also called collars). Without them, plates can slide off during the lift, which is dangerous. The only exception is bench press where some lifters prefer no clips as a safety measure.
