Heart Rate Zones for Age 49: Target BPM for Every Training Zone
Estimated maximum heart rate at age 49: 171 BPM (220 − 49 formula). Average resting HR for this age group is approximately 72 BPM. The five zones below define effective training intensity ranges.

The 220−age formula has a standard deviation of ±10–12 BPM — meaning true max HR at age 49 could reasonably range from 159 to 183 BPM. For a more accurate estimate, a graded exercise test (GXT) is the gold standard.
To measure your heart rate: place two fingers on your carotid artery (side of neck) or radial artery (inside wrist) and count beats for 15 seconds, then multiply by 4. A chest strap heart rate monitor is the most accurate wearable method.
