If you are new to strength training stats, the numbers can feel technical. This short guide explains the most common metrics you see in Gymfile.
1RM is an estimate of how much weight you could lift for a single repetition. It’s calculated from the sets you log, and it’s a simple strength benchmark to track progress over time.
Max 1RM is the highest estimated 1RM from all of your sets. It represents your best top-end strength for that exercise.
Avg 1RM is the average estimated 1RM across your completed sets. It is more stable than Max 1RM and helps track day-to-day strength trends.
Volume is the total weight lifted for an exercise, summed across sets:
Volume = Σ(weight × reps)
For time-based exercises, Gymfile uses Load-Time instead of Volume. It is calculated as:
Load-Time = Σ(time under load)
This helps compare performance when reps are not the primary measure.
If 1RM goes up, you’re getting stronger. If Volume goes up, you did more total work. Volume can change a lot just by adding or removing sets, because it measures how much work you did in total—not your strength level like 1RM.
Together, 1RM and Volume show both intensity and total work. That combination helps you understand progress, manage fatigue, and keep training balanced.
