More than the weight on the bar.

Your bench may not have gone up 10 pounds, but you may be doing more reps at the same weight or completing the same work with less effort. Those trends are worth reviewing alongside load, rather than treating any one result as proof of a strength gain.

Iron Progression tracks eligible single-rep performances and estimated 1RM automatically. An estimated one-rep max is calculated from weight and reps; it is not a tested maximum or a prediction that you can safely lift that weight today.

Milestones, not a reason to max out.

The app doesn’t encourage chasing PRs every session. It tracks the milestones your training produces and surfaces them when they arrive. A milestone is a record to review, not an instruction to attempt a heavier lift.

Official estimated 1RM uses eligible loaded, rep-based sets of 1 to 10 reps. Warmups, backoffs, drops, clusters, and other excluded set types do not feed that record. Bodyweight-only, assisted, duration, and distance work are not treated as loaded 1RM tests.

How to read a new record.

Check that you logged the right exercise, load, reps, and set type. Then compare similar technique and range of motion. Changing a movement or shortening the rep can change the number without demonstrating the same improvement.

Use effort ratings and Reports for context. A record is one observation; repeated performances tell you more than a single best day.
