This tool is actually quite good. being able to build a time weight workout with cues as to weights reps and exercises. The list of exercises available in the workout builder for strength training activities is quite good. however...it can never be comprehensive. there are too many out there.
1) problem: all exercises desired in a given workout are not available in the exercise picker within the workout builder
request: would be nice to have the ability to add user defined exercises to this list. doesn't seem like it would be too cumbersome to do so. e.g. rather than just having 1 arm dumnbbell rows" with a note (which you can't read effectively on the watch during the workout) about the position you are doing it in (bent over, plank, etc) you could add exercise "1 arm DB rows in plank"...other examples exist where the exercise is entirely not in the list. a good example of this is stretches...there are in fact only 2 listed. i might like to add specific stretches to my workout.
2) problem: unit of measurement for weights isn't correct
for some reason (maybe i'm missing something?) the watch is changing my unit of measure. on my workout builder and in my settings i have units set to LBS. on the watch during the workout, however, it changes the unit to KG then converts it back (incorrectly) to lbs in the logged activity. e.g. i've entered "20 lbs" in the workout builder for an individual exercise and during the workout it prompts me "20 KG" (which could be worse..at least i know which dumbbell to pick up)..but when it uploads the activity afterwords...it converts "20 kgs" (from the watch) to "44 lbs" in the log. this is problematic for progress tracking.
