For instance the Whoop 4.0 and Garmin Instinct 2 also did a good job here. Now, if you want the best battery life out of a device, and pretty good heart rate tracking during cycling, then I would recommend the Garmin Instinct 2. If you just care about heart rate tracking, and you do not need a smartwatch, I would just buy an ECG chest strap, like the Polar H10, which will give the most reliable results. ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ Timestamps: 00:00 Intro 01:29 Overview of Tested Watches 02:05 Test Design 03:18 Test 1: Indoor Cycling (Easy) 09:09 Test 2: Outdoor Cycling (Medium) 12:54 Test 3: Weight Lifting (Hard) 15:50 Recommendations and Conclusions
