Learn why MAF, Karvonen and a watch’s zone label disagree, then use that understanding to prepare better questions about effort. By [Ken Gardner](https://fruitfulyears.com/ken-gardner/) · Published August 19, 2026 ![Older man checking his heart rate while walking outdoors for Zone 2 exercise](https://fruitfulyears.com/wp-content/uploads/2026/08/Zone-2-heart-rate-after-60-walking-workout-1-1024x572.jpg) ## Quick takeaways - **Different formulas answer different questions.** Their results are not interchangeable. - **Medication matters.** Heart-rate-altering medicines can make standard targets misleading. - **Symptoms outrank the number.** Comfortable conversation is an effort cue, not a safety certificate. Educational guidance. Not medical advice. Discuss training or dietary changes with your physician. ## Heart-rate formulas and their limits The [Tanaka study](https://pubmed.ncbi.nlm.nih.gov/11153730/) concerns estimated maximum heart rate, not a directly measured Zone 2 threshold. “Zone 2” also varies across coaching and device systems. Trying to force your pulse into an age-based bracket can turn an intended easy session into something else. [AHA guidance on beta blockers and exercise](https://www.heart.org/en/health-topics/consumer-healthcare/medication-information/how-do-beta-blocker-drugs-affect-exercise) explains why medication context deserves individual advice. ## Compare MAF, heart-rate reserve and the talk test ### MAF 180 **Why it matters:** A simple coaching rule is not a measured physiological boundary. **Practical application / what to track:** The illustration 180 minus age gives 115 bpm at age 65; do not treat it as a personal safety ceiling. ### Karvonen arithmetic **Why it matters:** Heart-rate reserve includes resting pulse and a chosen intensity percentage. **Practical application / what to track:** Target = resting pulse + (estimated maximum minus resting pulse) × intensity fraction. Ask how the fraction was selected. ### Compare like with like **Why it matters:** Percent of maximum and percent of reserve describe different calculations. **Practical application / what to track:** For age 68 and resting pulse 58, a rounded Tanaka maximum of 160 gives about 99–118 bpm at 40–59% reserve. This is arithmetic, not a prescription. ### Effort and symptoms **Why it matters:** Breathing, terrain, fatigue and symptoms add context that a watch cannot supply. **Practical application / what to track:** Record the activity, pulse and perceived effort together. The [CDC talk-test guide to relative exercise intensity](https://www.cdc.gov/physical-activity-basics/measuring/index.html) describes moderate effort as being able to talk but not sing. This is a general effort cue, not a measurement of your personal Zone 2 threshold or a safety test; do not increase effort merely to reach a displayed zone. ## Heart-rate targets that can mislead - **Calling 60–70% heart-rate reserve “easy Zone 2.”** It is not the same as 60–70% of maximum. - **Changing medication to reach a training number.** Never do this. - **Ignoring a disagreement between symptoms and a device.** Stop and seek guidance when needed. **Do not push through warning symptoms.** Stop activity and seek help for new or unexplained symptoms. For possible heart-attack or stroke symptoms, fainting or severe breathing difficulty, call 911 or your local emergency number. A comfortable pace or watch reading does not guarantee safety. ## Questions for your clinician about medicines, intensity and symptoms Use the questions that fit your situation. Keep personal health notes private and bring them through your clinic’s approved channel. - **Does my medication or health history change how I should judge intensity?** - **Would a talk test, perceived effort or supervised assessment be most useful?** - **What symptoms or changes in exercise tolerance should I report?** ## Next steps and related reading Choose one useful next step rather than adding several new tasks at once.
