In modern training science, the two metrics most strongly associated with hypertrophy are progressive overload of volume per exercise (e.g. Plotkin 2022) and weekly hard sets per muscle (e.g. Schoenfeld 2017, Pelland 2025).

BTB Workout Log is a workout tracker built to follow exactly these two — with nothing in the way.

■ LOG SETS, WATCH MUSCLES ADD UP Just log weight, reps, and sets. BTB maps each exercise to the muscles it works, so weekly hard sets per muscle — chest, back, shoulders, arms, legs — are tallied automatically. Volume and estimated 1RM trends per exercise show progressive overload in numbers, not by feel.

■ FAST BECAUSE WE LEFT THINGS OUT No social feed, no rest timer, no tutorial videos, no templates. Logging and analysis only — that's why it's light. Last-time suggestions and a custom keypad finish your input in the seconds between sets.

■ KEY FEATURES • Weekly hard sets per muscle, tallied automatically • Volume & estimated 1RM trend charts per exercise • Fast entry with last-time suggestions + custom keypad • CSV export (even on the free plan) • Fully offline, zero ads

Catch undertrained muscles before they stall your progress. Balance your week by the numbers, not by feel.

"BTB" stands for "Better Than Before."
