❤️ Understanding Heart Rate

Maximum Heart Rate (MHR): Highest beats your heart can pump in a minute. Decreases with age.

Resting Heart Rate (RHR): Your heart rate at complete rest. Lower = better cardiovascular fitness. Athletes can have 40-60 bpm.

📐 The Formulas

Maximum HR (Tanaka, 2001):

MHR = 208 − (0.7 × age)

Karvonen Formula (Most Accurate):

Target HR = ((MHR − RHR) × intensity%) + RHR

This accounts for your fitness level by including resting heart rate.

🎯 Which Zone for Which Goal?

🔸 Beginner: Spend most time in Zones 1-2

🔸 Weight loss: Zone 2 burns highest % of fat

🔸 Endurance: Zone 3 builds aerobic capacity

🔸 Performance: Mix Zone 2 (long sessions) + Zone 4 (intervals)

🔸 HIIT: Brief bursts in Zone 5, recovery in Zone 1

💡 How to Measure Heart Rate

✅ Smartwatch: Most accurate, measures continuously

✅ Chest strap: Even more accurate than wrist

✅ Manually: Place 2 fingers on wrist or neck, count beats for 15 sec, multiply by 4

⚠️ Important: Consult a doctor before starting intense exercise, especially if you have heart conditions, are over 40, or new to exercise. Stop immediately if you feel chest pain or dizziness.
