The plates for every set, already worked out
No more adding up plates between sets. Every barbell set in Liftsmith shows which plates go on each side, drawn on the bar, from the plates your gym actually has.

Your plates, your bar
Set up your gym's bars and plates once: an Olympic bar, a women's bar, a trap bar, an EZ bar, and how many of each plate. Planned weights are rounded to totals you can actually load, so the plan never asks for 101.25 kg with no 0.625 kg plates in sight.
Kilograms or pounds, with the colours lifters expect, and a quick note of what's already on the bar so you change as few plates as possible.
On the web too
The same plate math is free in your browser in the plate calculator. Our guide on how to load a barbell covers the basics.
