Why a Heart Rate Fitness Band Beats Wrist Watch Sensors
Most smartwatches use optical (wrist-based) sensors. They're convenient but can be off by 5–10 bpm during HIIT, running, or cycling — especially if you have tattoos or move a lot.
A dedicated heart rate fitness band (chest strap or armband) uses ECG or high-quality optical tech and stays rock-steady. Studies and 2026 reviews (Runner's World, PCMag, REI) consistently show chest straps are the gold standard for serious athletes.
