If you constrain the device to ‘fitness tracker” and not lifestyle/sleep/health/illness/fitness telemetry, sure.

I wear an Oura Ring for the complete suite of telemetry, not just for tracking workouts.

I also lift, I’ll take the ring off for heavy lifts, and keep it on for every other exercise (unless I feel there’s a risk that the ring could get caught on the equipment, in which case I’ll take it off for those reps too). Granted this is in my home gym, so there’s no inconvenience to me doing this.

I’ll rest between exercises and that’s when I make the call to keep the ring on or not [for the subsequent exercise].

I still get most of the insights and the Oura ring app lets me to tell it that I was doing strength training, which allows it to guesstimate calorie usage based on duration.

Of course that’s not perfect, but it’s good enough for people who are interested in health metrics without being obsessed with them (which is just probably a better idea unless you’re a pro athlete).

The workout tracking is kinda the least interesting aspect for me. It’s more about the long term trends of activity, sleep, heart rate, stress, etc.

Also, it’s worth saying, I went with a ring rather than a watch or a band because I like to wear a real watch.

I'd question the utility of the data from a ring for weightlifting, cardio sure but just lifting weights there's not a huge need to track your heart rate, you're not moving a lot for steps, etc.
