- How much does an Olympic barbell weigh?
- A standard men's Olympic barbell weighs 20 kg (44 lb), commonly rounded to 45 lb in US gyms. A women's Olympic bar weighs 15 kg (33 lb, often called 35 lb). Technique bars and many home-gym bars weigh less, so check yours.
- Should I count the collars?
- Spring clips weigh almost nothing, but competition collars weigh 2.5 kg each (5 kg per pair). If you use heavy collars, turn on the collar option so the calculator subtracts their weight.
- Why can't the calculator hit my exact target?
- You can only load in steps of twice your smallest plate (one on each side). If the target can't be reached exactly with the plates you've selected, the calculator loads the closest weight below it and tells you the difference.
- What plates should a home gym have?
- A practical starter set in pounds is 2×45, 2×25, 2×10, 2×5 and 2×2.5, with extra 45s as you get stronger. Fractional plates (1.25 lb or 0.5 kg) help with small jumps on presses.
