The video consists of a review of the Koros Pace 2 optical heart rate sensor for CrossFit workouts. The YouTuber highlights features like workout analysis and recovery time but expresses uncertainty about training load and missing data. The importance of accurate heart rate tracking is emphasized, especially in different heart rate zones. Testing shows the Koros Pace 2 has inaccuracies in heart rate monitoring during intense workouts, with accuracy as low as 40%. Comparisons with Garmin and other major brands show shortcomings in the Koros Pace 2's performance, suggesting the need to consider pairing it with a chest strap for better results. Overall, relying solely on the watch's wrist-based heart rate tracking for intense workouts is not recommended.

In this segment of the video, the YouTuber reviews the Koros Pace 2 optical heart rate sensor for CrossFit workouts. They highlight features they like such as workout analysis and recovery time, but express uncertainty about training load over time and missing sleep and wellness data. The importance of accurate heart rate tracking during CrossFit is stressed, with emphasis on the comparison between the device’s wrist-based optical heart rate sensor and a chest strap for accuracy in different heart rate zones (average, 80-100% of max heart rate, and peak zone 90-100% of max heart rate). Testing accuracy in these zones is crucial for reliable workout analysis and tracking performance over time.

In this segment of the video, the speaker discusses the optical heart rate accuracy of the watch during workouts. They found the accuracy to be only 40%, indicating the need to pair the watch with a chest strap for better results. After testing the watch for three workouts, they concluded that relying on wrist heart rate tracking for high-intensity workouts like CrossFit is not recommended. The speaker suggests considering the watch as a higher-priced model with the additional cost of a chest strap. Overall, the watch’s performance with heart rate accuracy for intense workouts was deemed inadequate compared to other major brands like Polar, Suunto, and Garmin.
