MAF Heart Rate at Age 55
Using Dr. Phil Maffetone's 180 Formula, your baseline aerobic training heart rate at age 55 is 125 bpm. Adjust based on your health and training history.

Adjustments for age 55
The 180 Formula isn't a single number. Dr. Maffetone designed it with four adjustment bands so the ceiling matches where your body actually is right now, not just your calendar age.
| Your situation | Formula | MAF HR |
|---|---|---|
| Recovering from major illness, surgery, or on regular medication | 180 − 55 − 10 | 115 bpm |
| Inconsistent training, recent injury, frequent colds, or new to MAF | 180 − 55 − 5 | 120 bpm |
| Consistently training 2+ years, no major health issues (default) | 180 − 55 | 125 bpm |
| Competitive athlete with measurable MAF-test progress over 2+ years | 180 − 55 + 5 | 130 bpm |

MAF training at age 55
At 55, the 180 Formula's standard subtraction often leaves too much on the table for healthy, consistently training athletes — and too little headroom for those recovering from any health event. Dr. Maffetone's canonical guidance: if you're in excellent health with 2+ years of unbroken training and measurable MAF-test progress, add 5 bpm to the 180 − age result. If you're managing any chronic condition or medication, subtract 10. Listen to the signal: your MAF test pace trend over 2-3 months tells you if the number is right.
Frequently asked questions
What is my MAF heart rate at age 55?
Using Dr. Phil Maffetone's 180 Formula, your baseline MAF heart rate at age 55 is 125 bpm (180 − 55). Adjust ±5 to ±10 bpm based on your health and training history. Your MAF training zone is the 10 bpm window below this ceiling, so 115–125 bpm.
Is 125 bpm too low for a 55-year-old?
It will feel too low for the first weeks, especially if you're used to running or cycling harder. That's the point: the MAF zone is where your aerobic system develops without the stress response that breaks down tissue and suppresses the immune system. Within 8-12 weeks of consistent training at this HR, your pace at 125 bpm starts improving — that's measurable aerobic fitness gain.
How do I know if I should subtract or add from 180 − 55?
Subtract 10 if you're recovering from a major illness, surgery, or take regular medication. Subtract 5 if your training has been inconsistent, you've been injured in the past 6 months, or you've had more than 2 colds this year. Use the standard result (180 − 55) if you've been training consistently for 2+ years with no major issues. Add 5 if you're a competitive athlete making measurable progress in your MAF tests.
