Frequently asked questions
- What is the Karvonen formula?
- Karvonen target HR = (Max HR - Resting HR) × intensity% + Resting HR. It gives more personalised zones than simple percentage-of-max because it accounts for your cardiovascular fitness.
- Which zone is best for fat burning?
- Zone 2 (60–70% of max) is the classic fat-burning zone. Higher zones burn more total calories but use a higher proportion of carbohydrates.
