Is the new Garmin Strength Coach any good?

Overall, its a great product, works good now and a lot of improvements can be made.  Much easier to use than a smartphone app because the watch is always on your wrist, you don't have to put it down, pick it up, and get interrupted by an incoming call.

I'm not quite a serious lifter - but am more than casual.

Pro:

1. good selection of exercises,

2. weight increases each week, based on 1 rm

3. rest timer, and other stats built in.

4. rest week, 1rm recalculation week built in.

Con:

1. only two primary exercises show weight to put on bar.  the 4 secondary exercises don't so I have to remember them (and I don't remember correctly all the time.)

2. Indication of last set in group is not obvious except in 1rm reevaluation week.  I'd like some clear indication of the last set so I can do more reps than what the watch calls for. 

3.  I haven't found how to select machines as opposed to "dumbbells only" or "full gym".  the full gym setting selects only barbells, dumbbells a few cable machines, and benches.  I'd like to have a primarily machine workout for coach.   That would need a separate 1rm calculation.

4. I would like to substitute a few machines in a barbell routine, like a pec deck for dumbbell flys

6. I'd like a place to add sit-ups and related abb exercises.  It could go with the 1 hour  "leg day"  to make a 2 hr leg and gut day.

7. I'd like a way to specify minimum weight increments - eg 10 lbs (5 lbs on each side of the bar) or even 5 lbs (2.5 lbs on each side).  I'm not going to use smaller weights)

8.  The intro to each bar exercise should show weight as 45 + 30 + 30 , that is, weight of bar plus load on each end of  bar.  Ideally I could change the weight of each exercise's bar (one gym had 35 lb ez-curl bars). or select a bar for that exercise - eg 45 lb Olympic Bar, 35 lb EZ-Curl bar, etc). 

9.  Need a way to substitute other exercises on occasion.  E.g. If I am in a hotel gym, I may have dumbbells and machines but not barbells.  So I may want to do dumbbell bench presses instead of barbell ones.

9. specify weight for dumbbells to be entered as the weight of one dumbbell.  Do calculations using 2 dumbbell weight as needed.  This may affect calories burned an other metrics.
