A family fitness log that isn't tied to a wearable subscription.
Your household's step counts, cycle data, and weight trend are among the most valuable data a wearable company sells. Keep them.
Fitness data went from a Fitbit fad to a subscription category to an insurance-adjacent one, quickly. If your household would rather log the workouts than lease access to the log, a file is a very reasonable option.
One file per person
Workouts, walks, weight, resting heart rate if you take it, notes on how it felt. Chronological. Yours.
For the household that trains together
Shared file for the couch-to-5K, individual files for the personal-best chasing. Same tool, different unit of use.
Compatible with any hardware
Wear a Garmin, wear nothing — the log doesn't care. Type in what happened; that's the record.
What to reach for
Common questions
Does it sync from my watch?
No — deliberately. The point of typing is the noticing. If you want automatic capture, keep your watch app for that and use this for the training plan.
Programmes?
Bring your own — 5x5, PPL, whatever. The Workout Log is a container, not a coach.
Weight trend?
Simple line chart, in-file. No 'insights', no scoring.
Cycle tracking?
Use the Health Log's cycle section — private on your machine, which for cycle data specifically is the right posture.
