I don’t trust the heart rate sensors on watches, so wear a chest strap on every run — here are the 4 best straps I’ve tested
The author explains why they prefer chest strap heart rate monitors over smartwatch optical sensors for running. While modern watches like Garmin and Apple have improved accuracy, the article argues that chest straps still provide more reliable data for training intensity and recovery analysis. The piece reviews four top-performing chest straps and offers buying guidance.
- ▪Optical heart rate sensors on watches can produce inaccurate readings, especially when used to gauge effort during varied-intensity training sessions.
- ▪Chest straps measure heart rate via electrical signals from the chest, which generally yields more consistent and precise data than optical methods.
- ▪The author tested four chest strap models and concluded that using a strap for every run offers the most reliable performance metrics.
- ▪Even high-end watches such as Garmin and Apple have narrowed the accuracy gap, but the author still finds them insufficient for detailed training analysis.
- ▪The article includes affiliate links and encourages readers to consider the reviewed straps as essential accessories for serious runners.
