Max Heart Rate: 180 BPM
At age 40, your estimated maximum heart rate is 180 BPM. See your target training zones below.
How This Works
This uses the standard "220 minus age" formula to estimate maximum heart rate, then applies percentage ranges to define training zones for different exercise intensities. Individual fitness levels vary, so these are general guidelines — a fitness professional or doctor can help tailor zones to your specific fitness or health situation.

Frequently Asked Questions
What is the maximum heart rate for a 40-year-old?
Approximately 180 beats per minute (BPM), using the 220-minus-age formula.
What heart rate zone is best for fat burning?
The moderate zone (roughly 60-70% of max heart rate) is often cited for fat burning, though total calories burned across all zones matters more than the specific zone for overall fat loss.
