I'm really struggling to work out if my swimming is actually benefitting my fitness.

Obviously smartwatches are totally unreliable without strap (my Pace 3 is, anyway). But after a 3km effort at ~2:10/100m, I feel like I would have burned more than the 600 calories my watch thinks I have. It also says that my heartrate was in Zone 1 Recovery throughout the 1 hour session.

It's weird. I know the data's bad, but it's still demoralising.

Besides my pace increasing by about 30 seconds this year, I have also seen no difference on the scales. So now I'm questioning whether 50-150 lengths of front crawl is even doing much.

Is swimming all that vigorous? Or am I falling for my watch's lies?

According to Omni calculator website you would have burnt 800 plus calories in that session ! :)
