| Our verdict | Fitbit's slim form factor makes it unobtrusive for 24/7 wear and baseline recovery metrics. The optical sensor will exhibit latency during interval sessions, making a dedicated chest strap necessary for high-intensity work. Buyers should note that long-term historical health trends and advanced sleep breakdowns sit behind a paid Fitbit Premium subscription. | The benchmark electrical chest strap for athletes requiring immediate heart rate response during interval work. Dual Bluetooth and ANT+ broadcasting allows simultaneous connection to bike computers and training apps without dropouts. At roughly $99, it commands a premium over basic straps, but delivers unmatched data reliability. |
