Prone Back Extension Pull-Down

Practice history covers September 28 – October 25, 2026. Difficulty and clarity come from the app’s exercise content.

1. Times practiced. One record per exercise per saved workout. We count the exercise when it is marked complete, the workout is marked complete and its logged duration is positive. This movement has 769 counted records in this window. A repeated practice in another workout adds another record. Zero means no qualifying record was found in this window.
2. Popularity. A count ranking within the men’s track. Only exercises with counted practices are ranked; equal counts share a place. Plan placement and repeat users affect the ranking.
3. Days per active week. We count different local practice dates for each account in each Monday–Sunday week, then average those counts. Only weeks when that account practiced this exercise are included. Here that is 763 account-days ÷ 619 active account-weeks. We show the average when at least 10 accounts contributed. It describes this history; it is not a recommended weekly schedule.
4. Difficulty. 2/5 — lower demand on the app’s content scale. Higher means more demanding. This is a fixed exercise score; it is not calculated from usage or a personal assessment.
5. Clarity. 3/5 — middle of the scale on the app’s content scale. It describes how clearly the instructions and demonstration specify the movement. This is a content score, not a percentage of users who understood it or an average user review.
6. In a workout. The movement’s default time block in the app. Pauses and settings can change elapsed practice time. It is not a repetition count.

These are saved app records, not verified repetitions or movement quality. Anonymous, unsynced and deleted histories can be missing. Accounts are not a one-to-one count of people, and this snapshot has no comprehensive staff/test-account exclusion.
