logr is a workout logger built on hypertrophy research, for evidence-based lifters. It records every variable that changes what the numbers from a lift mean, and shows how they add up over months.
the problem
Incline Press · 100 kg x 8
Incline Press · Plate Loaded · Prime
bilateral · peg 3 · seat 4 · neutral grip · tempo 3-1-1-0
100 kg x 8 · 1 RIR
A log that can't show you any of this isn't telling you much. Lifters who care about that outgrow their tracker.
what logr does
First, the basics, because a logger has to get progressive overload right: last session's numbers beside every set, rest timers for each set type, PRs flagged when you finish, and templates.
Then come the details only logr captures, and the long view they make possible.
The detail
Every set is tied to the equipment model you used, by load type, brand and model. History and equipment settings are kept per machine, and one exercise can be compared across two of them.
An execution is how you perform a lift: a grip, a body position, a technique. Each keeps its own history. Sets can be bilateral, unilateral or alternating, with tempo in four phases.
New exercises appear all the time, often on machines built for something else. Create your own, link it to a real machine and record the attachment, GymPins and cuffs included.
The long view
This is the weekly number we put first. Set a target range per muscle group and logr marks what falls under it and what goes over. Warmups never count.
Plan by weekday or as a repeating cycle, rest days included. Your calendar shows planned days, the dashboard shows the next workout, and a missed day can re-flow or stay put.
logr charts every exercise and machine, flags PRs with an estimated one-rep max, and tracks average RIR or RPE, muscle frequency and your weeks across the year. One hard session barely means anything here.
You don't have to be advanced to use it, or call yourself a science-based lifter. The simpler workout view is weight and reps, the advanced view adds the rest, and you can switch anytime.
Moving over is quick too. logr imports your history from existing tracking apps, and it can read a workout template out of any screenshot, wherever it came from.
