@mikesweber1, you can log sets as laps with whatever device you’re using to record your workout. Below are two screen captures of a weight lifting session I did earlier in the week.
This is the summary screen. I’ve manually entered the exercises and weights in the notes field, and for this workout every four exercises are a set (i.e. 1-4, 5-8, 9-12, etc). I hit the Lap button on my watch between sets
This screen contains the details and shows heart rate and the laps (i.e. sets). There are more metrics below this but hopefully you get the idea.
