Enter information in left column; enter weights and select
appropriate menu if required. If needed, modify Weight Plate
Pairs 'Available' according to your inventory. Click "Calculate".
Calculate number of weight plate pairs needed on barbell (plates
on each side) to reach closest weight without exceeding target
weight. If it is not possible to reach the target with the available
weights, a value greater than 0 (Target Weight - Final Weight)
will appear in the 'Difference' field.

Percentage pulldown field can be used to calculate required
weight plates for either warm up set(s) or a specific percentage(s)
of a 1RM. If weight of the collars should not be included as
part of the final weight, select 'None' for Collars. Approximate
weights of barbell and collars are provided below. Exact weights
may vary. 'Bar Weight' can also be used to indicate the weight
of a sled on a leg press or hack squat machine.
