How it reaches your watch
Press Save here, then on the watch open
Settings → Sync → Sync now. Your workouts appear at the top of the
Programs list, above the seven built-in programs, and run exactly
like them — same set timer, same rest timer, same personal bests, same activity
saved to Garmin Connect.
Syncing needs your phone connected, so do it before you head out — not mid-workout.
Up to 10 workouts, 20 exercises each and
60 sets per workout, with up to 12 sets per exercise
on GYM Power Pro v3.4.0 or later. A target weight is optional: leave it blank and
the watch prefills from your own history, exactly as it does today.
Choose Custom exercise… to enter your own name, muscle group and
tracking type. Custom exercises keep their own history and personal records even if
you rename them later.
Keep names short. On a small watch a menu row shows about 12 characters before it is
cut, so Upper Body Push A and Upper Body Push B would look identical
in the list — the builder will ask you to change one.
