Use each tool for a specific task: recording a set, totaling equipment or inspecting a training record.
A log records results
Keep completed weights and repetitions in the app. Notes explain the equipment convention; the routine describes the plan.
A calculator handles arithmetic
The barbell tool totals entered bar and plate mass. The volume tool adds weight multiplied by repetitions. Neither calculation chooses a suitable training load.
An export supports inspection
A PDF report and CSV data can be reviewed outside the app. Check file contents before relying on a spreadsheet workflow, and keep private records in a location you control.
Use each tool for a specific question
A barbell calculator answers how much is loaded. A volume calculator adds weight multiplied by repetitions. A workout log records the individual sets and context. For example, three 50 kg sets of 8, 8 and 6 repetitions total 1,100 kg·reps, but that number cannot tell you whether the final set used different equipment. Keep the set record alongside any calculation so the summary remains traceable.
Make the calculation reproducible
Write down the inputs, units and inclusion rules. If one comparison includes warm-up sets and another excludes them, their totals answer different questions. Likewise, a per-hand dumbbell convention cannot be mixed with a combined-pair convention without adjustment. Use the website’s tools to inspect arithmetic, not to choose a training load or infer muscle growth. When you export records, keep an unchanged original file and make calculations in a working copy.
