What are heart rate training zones?

Training zones divide your heart rate range into 5 intensity bands: Zone 1 (50-60%) = warm-up/recovery; Zone 2 (60-70%) = fat burning/base endurance; Zone 3 (70-80%) = aerobic fitness; Zone 4 (80-90%) = lactate threshold; Zone 5 (90-100%) = maximum effort.

What is the Karvonen formula?

The Karvonen (heart rate reserve) formula is more accurate than simple maximum HR percentages. It accounts for resting heart rate: Target HR = ((Max HR - Resting HR) x Intensity %) + Resting HR. This gives a personalized zone that reflects your individual fitness level.

How do I measure my resting heart rate?

Measure first thing in the morning before getting out of bed. Count your pulse for 60 seconds. A typical resting HR is 60-80 bpm. Athletes often have 40-60 bpm. A lower resting HR generally indicates better cardiovascular fitness.

Is the fat burning zone the best zone for losing weight?

Zone 2 burns a higher percentage of calories from fat, but higher zones burn more total calories per minute. For overall fat loss, total calorie deficit matters most. Zone 2 is ideal for long sustainable sessions; higher zones for short intense sessions.
