Find the weight to load on each side of a barbell.

Target weight

Bar weight

Weight per side 40

Total plate weight 80

Formula: per side = (target − bar) ÷ 2

Step-by-step with your numbers:

1. Values used:

2. Target weight = 100

3. Bar weight = 20

5. Weight per side = 40

6. Total plate weight = Target weight - Bar weight = 100 - 20 = 80

Did we solve your problem today?

Find how much to load on each end of the bar.

The math behind it

plate weight = target − bar; per side = that ÷ 2. A standard Olympic bar is 20 kg (45 lb).

100 kg with a 20 kg bar → 40 kg per side.

Negative?

Target is below the bar's own weight.
