Introduction
Understanding how to calculate zone 2 is critical for athletes, coaches, and fitness enthusiasts who focus on heart rate training to optimize performance and endurance. Zone 2 training is essential for developing aerobic capacity and improving overall cardiovascular health. This zone is typically defined as maintaining a heart rate at 60-70% of your maximum heart rate, which promotes fat burning and endurance improvements. The precise calculation of this zone ensures that training is both effective and safe, maximizing benefits while minimizing risks.
In the following sections, we will delve into the methods to accurately determine your zone 2 heart rate. Additionally, we'll explore how Sourcetable simplifies this process and more with its AI-powered spreadsheet assistant, which you can try at app.sourcetable.com/signup.
How to Calculate Zone 2 Heart Rate
Understanding Zone 2
Zone 2 is crucial for boosting endurance and enhancing the efficiency of using fat and carbohydrates as fuel. It is typically defined as 73% to 80% of your maximum heart rate (HR).
Estimating Maximum Heart Rate
The formula 220 - age provides a quick estimate of your maximum HR. This estimation acts as a foundational step in calculating your Zone 2 HR.
Field Testing
A field test is considered the most accurate method to determine your actual maximum HR. Common methods include a well-controlled hill run test, which could also utilize tools like the MyProCoach zone calculator.
Alternative Methods
For those without access to testing facilities, monitoring breathing rates during incremental exercise can indicate the first ventilatory threshold—a marker for the beginning of Zone 2. Additionally, measuring lactate levels, though less practical for everyday athletes, offers precise determination.
Using Online Calculators
MyProCoach provides an online zone calculator that utilizes either the age-based formula or inputs from a physical test to estimate HR zones. This tool can personalize training plans to heart rate zones, enhancing the accuracy of your Zone 2 training.
Other Formulas and Ratios
For a different approach, the MAF Formula 180 - age - 5 specifically tailors Zone 2 calculations. Moreover, using 83% to 88% of your anaerobic threshold HR can alternatively define the upper Zone 2 limits, aligning with aerobic threshold considerations.
How to Calculate Zone 2 Heart Rate
Understanding Zone 2
Zone 2, often referred to as the aerobic, endurance, or base training zone, is defined as 60% to 70% of your maximum heart rate. It is crucial for improving endurance and the efficiency of using fats and carbohydrates as fuel. This zone is characterized by moderate intensity effort where you can still maintain a conversation.
Estimating Maximum Heart Rate
The most common method to estimate your maximum heart rate is the formula 220 - age. This foundational value is critical for calculating your Zone 2 heart rate which focuses on fat burning and maintaining a prolonged exercise effort without exhaustion.
Calculating Zone 2 Heart Rate
Once you have estimated your maximum heart rate, calculate your Zone 2 heart rate by multiplying this number by 0.60 and 0.70. For instance, for a 30-year-old, the maximum heart rate would be 220 - 30 = 190 bpm. Therefore, the Zone 2 heart rate ranges from 190 x 0.60 = 114 bpm to 190 x 0.70 = 133 bpm.
Determining Intensity Through Different Methods
Besides mathematical calculations, you can refine your Zone 2 intensity through the "talking test" — ensuring you can hold a conversation comfortably during the exercise. Alternatively, use fitness trackers to monitor your heart rate during activities such as walking, jogging, or biking.

Examples of Calculating Zone 2 Training Intensity
Example 1: Using Maximum Heart Rate
To calculate Zone 2, first determine your maximum heart rate (MHR) using the formula 220 - age. Zone 2 is 60-70% of your MHR. For a 30-year-old, the MHR is 220 - 30 = 190. Zone 2 would then be 190 x 0.60 = 114 bpm to 190 x 0.70 = 133 bpm.
Example 2: Using Heart Rate Reserve
First, find your resting heart rate (RHR) and your MHR using the previous method. The heart rate reserve (HRR) is MHR - RHR. For an individual with an RHR of 60 bpm and an MHR of 190 bpm, the HRR is 190 - 60 = 130. Zone 2 is 60-70% of HRR, added to RHR: (130 x 0.60) + 60 = 138 bpm to (130 x 0.70) + 60 = 151 bpm.
Example 3: Using a Lactate Threshold Test
If you have done a lactate threshold test, identify your lactate threshold heart rate (LTHR). Zone 2 is typically 85-89% of your LTHR. For an LTHR of 160 bpm, Zone 2 would be 160 x 0.85 = 136 bpm to 160 x 0.89 = 142 bpm.
Example 4: Using Karvonen Formula
Employ the Karvonen formula combining MHR, RHR, and desired intensity. For MHR 190, RHR 60, and Zone 2's intensity range 60-70%, the calculation is ((MHR - RHR) x 0.60) + RHR = (130 x 0.60) + 60 = 138 bpm to ((MHR - RHR) x 0.70) + RHR = (130 x 0.70) + 60 = 151 bpm.
