Target Heart Rate Chart by Age: Complete Training Zone Guide

What Is Target Heart Rate?

Your target heart rate is the ideal range of heartbeats per minute during exercise that allows you to get the most benefit from your workout while staying safe. This range is typically expressed as a percentage of your maximum heart rate and varies depending on your training goals.

The concept of target heart rate zones was developed to help people exercise at appropriate intensities. Training too easy might not provide sufficient stimulus for improvement, while training too hard can lead to exhaustion, overtraining, and even injury. By monitoring your heart rate during exercise, you can ensure you're working in the zone that aligns with your specific fitness objectives.

Target heart rate zones are personalized based on your age because maximum heart rate naturally decreases as we get older. A 25-year-old and a 55-year-old working at the same percentage of their max HR will have very different actual heart rates, but both will be experiencing similar relative intensities.

Key benefits of using target heart rate zones include:

• Optimizing workout effectiveness for specific goals
• Preventing overtraining and reducing injury risk
• Ensuring adequate intensity for fitness improvements
• Providing objective feedback during exercise
• Allowing proper periodization of training programs
• Helping beginners learn appropriate exercise intensity

Complete Target Heart Rate Chart by Age

The following comprehensive chart shows target heart rate zones for different ages. Values are calculated using the Tanaka formula for maximum heart rate (208 - 0.7 × age), which research has shown to be more accurate than the traditional 220-age formula.

Target Heart Rate Zones: Ages 18-40

Target Heart Rate Zones: Ages 42-65

Target Heart Rate Zones: Ages 66-80

Understanding the Five Heart Rate Training Zones

Each heart rate zone serves a specific purpose in your training program. Understanding these zones helps you choose the right intensity for each workout and achieve your fitness goals more effectively.

Zone 1: Recovery Zone (50-60% of Max HR)

Zone 1 is the lightest intensity level, used primarily for warm-ups, cool-downs, and active recovery between harder training sessions. At this intensity, you should be able to carry on a full conversation without any difficulty. Your breathing is relaxed and easy.

Benefits of Zone 1 training:

• Promotes recovery between intense workouts
• Improves blood flow to muscles without creating additional fatigue
• Helps beginners build a foundation of cardiovascular fitness
• Reduces stress and promotes mental well-being
• Burns calories while minimizing physical stress

Typical activities: Easy walking, gentle cycling, light swimming, casual recreational activities

Zone 2: Fat Burning Zone (60-70% of Max HR)

Zone 2 is where your body primarily burns fat as fuel. This moderate intensity is sustainable for long periods and forms the foundation of endurance training. You can still hold a conversation, though you might need to pause briefly for breath between longer sentences.

Benefits of Zone 2 training:

• Maximizes fat burning as a percentage of calories burned
• Builds aerobic base and mitochondrial density
• Improves efficiency of fat metabolism
• Allows for high training volume without excessive fatigue
• Develops mental endurance for longer efforts

Typical activities: Brisk walking, easy jogging, moderate cycling, lap swimming at a comfortable pace

Zone 3: Aerobic Zone (70-80% of Max HR)

Zone 3 is the bread-and-butter zone for many fitness enthusiasts. At this moderate-to-vigorous intensity, you're working hard enough to make significant cardiovascular improvements. Conversation becomes more difficult - you can speak in sentences but need more frequent breaths.

Benefits of Zone 3 training:

• Improves cardiovascular efficiency and stroke volume
• Increases aerobic capacity (VO2max)
• Strengthens the heart muscle
• Burns significant calories
• Improves endurance performance

Typical activities: Running at a steady pace, tempo cycling, aerobic classes, swimming intervals

Zone 4: Anaerobic Threshold Zone (80-90% of Max HR)

Zone 4 is hard work. At this intensity, you're training at or near your anaerobic threshold - the point where lactic acid begins accumulating faster than your body can clear it. You can only speak in short phrases between heavy breaths.

Benefits of Zone 4 training:

• Raises your anaerobic threshold
• Improves speed and power
• Increases tolerance to lactic acid
• Enhances racing performance
• Provides mental toughness training

Typical activities: Tempo runs, hill repeats, high-intensity cycling intervals, competitive swimming

Zone 5: Maximum Effort Zone (90-100% of Max HR)

Zone 5 represents all-out effort that can only be sustained for very short periods - typically 30 seconds to 2 minutes. Speaking is nearly impossible, and breathing is at maximum capacity. This zone should be used sparingly and only by those with good fitness foundations.

Benefits of Zone 5 training:

• Develops maximum speed and power
• Improves neuromuscular coordination at high intensities
• Increases anaerobic capacity
• Triggers significant post-exercise calorie burn
• Simulates race-day demands

Typical activities: Sprinting, high-intensity interval training (HIIT), all-out efforts, race finishes

How to Use the Target Heart Rate Chart

Using a target heart rate chart effectively requires understanding your goals and matching them to the appropriate zones. Here's a practical guide to applying the chart to your training:

Step 1: Find Your Age on the Chart

Locate your age in the leftmost column. If your exact age isn't listed, use the closest age or interpolate between two values. Remember that these are estimates - individual variation of 10-15 beats per minute in either direction is normal.

Step 2: Identify Your Maximum Heart Rate

The second column shows your estimated maximum heart rate. This is the theoretical highest heart rate you can achieve during exercise. You generally won't train at this level except during short, all-out efforts. See our exercise heart rate by age guide for age-specific intensity recommendations.

Step 3: Select Your Training Zone Based on Goals

For weight loss: Focus primarily on Zones 2 and 3 (60-80% of max HR). While Zone 2 burns a higher percentage of fat, Zone 3 burns more total calories. A combination of both is most effective for weight management.

For general fitness: Spend most of your time in Zones 2 and 3, with occasional ventures into Zone 4. This builds a solid aerobic foundation while providing enough challenge to improve fitness.

For endurance events: Build your base in Zones 1 and 2, with Zone 3 tempo work and Zone 4 threshold training as you approach competition. Follow the 80/20 rule: 80% easy, 20% hard.

For speed and power: After establishing a base, incorporate more Zone 4 and Zone 5 training. However, these zones are demanding and require adequate recovery between sessions.

Step 4: Monitor Your Heart Rate During Exercise

Use a heart rate monitor (chest strap or wrist-based) to track your heart rate during workouts. Modern fitness watches make this convenient and provide real-time feedback to help you stay in your target zone.

Step 5: Adjust Based on How You Feel

Heart rate can be affected by fatigue, stress, hydration, temperature, and other factors. If a workout feels harder than the heart rate suggests, trust your body. The chart provides guidelines, not absolute rules.

Sample Weekly Training Plan by Zone

This plan follows the 80/20 training principle: approximately 80% of training time in Zones 1-2 and 20% at higher intensities.

Target Heart Rate Chart for Specific Activities

Different activities may produce different heart rate responses even at similar perceived efforts. Here's how to apply target zones to common exercises:

Running

Running typically produces higher heart rates than other activities at similar perceived efforts. For easy runs, aim for Zone 2 (60-70%). Tempo runs should be in Zone 3-4 (70-90%). Speed work and intervals will push you into Zones 4-5.

Cycling

Cycling heart rates are often 5-10 beats lower than running at similar perceived efforts because cycling is non-weight-bearing. Adjust your expectations accordingly - your "easy" cycling zone might feel easier than your "easy" running zone at the same heart rate.

Swimming

Swimming produces lower heart rates due to the horizontal body position and cooling effect of water. Subtract about 10-15 beats from your land-based zones when swimming. If your Zone 2 for running is 120-140, your swimming Zone 2 might be 105-125.

Group Fitness Classes

Classes vary widely in intensity. A yoga class might keep you in Zone 1-2, while a spin class or HIIT workout could push you through all five zones. Use your heart rate monitor to understand the actual demands of different classes.

Strength Training

Traditional strength training doesn't follow heart rate zones in the same way as cardio. Your heart rate will spike during sets and recover between them. Circuit training and metabolic conditioning workouts will maintain more consistent elevated heart rates.

Target Heart Rate Chart for Women

Research suggests that women may have different maximum heart rates than men of the same age. The Gulati formula, developed specifically from studying women, provides adjusted values:

Women may want to experiment with both the standard and Gulati-based zones to see which feels more appropriate during training. Our calculator allows you to compare results from different formulas.

Common Mistakes When Using Target Heart Rate Charts

Treating the Numbers as Absolute

Charts provide estimates based on population averages. Your actual zones could vary by 10-15 beats in either direction. If the chart says your Zone 3 is 130-145 but you feel like you're working in Zone 3 at 120, your personal zones are probably lower.

Ignoring Day-to-Day Variation

Your heart rate response varies based on sleep, stress, hydration, caffeine, heat, and other factors. A heart rate that's higher than usual at a given pace might simply mean you need more recovery, not that you're getting less fit.

Training Too Hard Too Often

Many people spend too much time in Zones 4-5, thinking harder must be better. Research consistently shows that most training should be easy (Zones 1-2), with hard efforts comprising 15-20% of total training time. This approach, paradoxically, leads to faster fitness gains.

Not Accounting for Cardiac Drift

During long workouts, heart rate naturally rises even if pace stays constant - a phenomenon called cardiac drift. This is normal and doesn't mean you should slow down to keep your heart rate in a specific zone during extended sessions.

Using the Same Zones for All Activities

As noted above, different activities produce different heart rate responses. Running zones don't directly translate to cycling or swimming zones. Adjust expectations based on the specific activity.

When to Recalculate Your Target Heart Rate

Your target heart rate zones should be updated periodically:

• Annually: Since maximum heart rate decreases with age, recalculate your zones at least once per year.
• After significant fitness changes: If you've been sedentary and start training, or if you've dramatically increased fitness, your actual max HR might differ from predictions.
• When zones don't feel right: If your calculated Zone 2 feels like Zone 4, your personal max HR is probably different from the formula's estimate.
• After illness or injury: Extended periods of reduced activity can affect cardiovascular fitness and heart rate response.
• When starting new medications: Beta-blockers and some other medications significantly affect heart rate. Consult your doctor about appropriate training adjustments.
