The product
One record of everything you lift
Planning, logging and analysis in a single app, so the numbers you train against are the numbers you actually recorded.
Method
Three steps, then repeat
- 01
Set the objective
Tell Grindly the goal, your training history and the equipment you have. It returns a split, a weekly volume target, and calorie and macro figures to match.
- 02
Record the work
Log each set as you complete it. Rest timers, exercise references and saved templates keep the session moving without breaking your rhythm.
- 03
Review what moved
Weekly reports show estimated one-rep max by lift, volume by muscle group, and adherence — so the next block is decided on evidence.
Included
The rest of the toolkit
Complete history
Every session you have logged, searchable by lift, date or template, with the exact loads and notes you recorded at the time.
Saved templates
Build a session once and reuse it. Templates carry your working weights forward and update as your numbers change.
Rest timing
Per-exercise rest targets start automatically when a set is logged, so the intervals you planned are the intervals you take.
Exercise reference
Over three thousand movements with execution notes and equipment variants, filterable by the kit you have available.
Encrypted sync
Your training record is encrypted in transit and at rest, and synced across your devices without leaving your account.
Reporting
Volume, frequency, intensity and adherence across any window you choose, exportable whenever you want the raw numbers.
Reviews
From people mid-programme
The plan rebuilt itself around a week I mostly missed, and it did it without wiping the progression I had already banked. Forty sessions in.
Logging is fast enough that I do it between sets without thinking about it. That is the whole battle with a training log.
Watching the estimated one-rep max line move is the first time a fitness app has shown me something I could actually act on.
I went from no structure at all to five sessions a week. Having the next session already decided removes the part I used to skip.
Calories, macros, sessions and progress photos in one record. I cancelled two other subscriptions the month I switched.
Quiet, quick and genuinely well thought through. It reads like it was built by someone who trains.
