BulkForged and Garmin Connect: what's saved where

A BulkForged workout is saved in BulkForged. It never becomes a Garmin Connect activity, lifting or cardio, today.

Where are lifting sets saved?

The watch tracks heart rate, distance and calories live while a cardio set runs.
That tracking never becomes a Garmin Connect activity. It is dropped once the set ends.
Distance, calories and heart rate for that set are saved in your BulkForged session instead.

The watch reads your heart rate during the set. It is saved in your BulkForged session.
With no GPS indoors, the watch records no distance or calories.
Type the treadmill's distance in on your phone, during the workout or afterwards.
On Android, calories come from Health Connect when it has a figure for that time.
Otherwise BulkForged estimates them from your bodyweight and how long you went.
You can type the treadmill's calorie figure in instead.

Connect Health Connect in Settings and your finished BulkForged workouts are sent there.
Each one lands as an exercise session, with your sets and weights written out in its notes.
A workout imported from Hevy or Strong is never sent to Health Connect. It is already in the app you imported it from.
Each bodyweight you log in BulkForged is sent there too.
BulkForged reads back in a bodyweight entry, and active calories for cardio estimates.
Sending workouts, sending bodyweight, reading bodyweight and reading active calories are all on by default. Each has its own switch in Settings, under Connected services.
Opening Connected services also reads your last 90 days of weigh-ins and workouts in Health Connect. It shows you how many are there.
That count has no switch of its own. Disconnect Health Connect to stop it.
