Heart Rate Zones for Age 24: Target BPM for Every Training Zone
Estimated maximum heart rate at age 24: 196 BPM (220 − 24 formula). Average resting HR for this age group is approximately 68 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 24 could reasonably range from 184 to 208 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.
