How to choose
- Heart Rate Accuracy During HIIT. CrossFit involves rapid heart rate spikes. Look for trackers with advanced optical sensors (like Polar's Precision Prime or Garmin's Elevate) that minimize lag. Chest straps are still best but wrist-based is good for convenience.
- Durability and Build Quality. Your tracker will take hits from kettlebells, barbells, and walls. Choose models with Gorilla Glass, military-grade standards (MIL-STD-810), or reinforced polymer cases. Avoid large watches that get caught on equipment.
- Battery Life. CrossFit training plus daily wear demands long battery life. Solar charging or multi-week battery is ideal. Consider how often you're willing to charge; mid-week charging can be a hassle.
- CrossFit-Specific Features. Some trackers offer rep counting, AMRAP timers, or CrossFit workout profiles. Garmin's Instinct 2 and Polar Pacer Pro have dedicated settings. If you track workouts manually, basic activity tracking may suffice.
- App Integration. Your tracker should sync seamlessly with apps like WODProof, SugarWOD, Beyond the Whiteboard, or Strava. Check reviews for sync reliability before buying, especially for Android users.
