Know Your Target Know Your Heart: Mastering Heart Rate Zones for Strength and Fat Loss
Most people don’t check their heart rate during strength training. But if you’re serious about burning fat, building lean muscle or just getting more out of your workout it’s time to understand your target heart rate. Knowing what’s happening inside your body whether you’re burning carbs fat or even using ketones is a game changer.
Why Heart Rate Matters During Strength Training

We usually link heart rate tracking with cardio but when it comes to fat loss understanding how your heart responds during strength training can help you
• Maximize your calorie burn
• Shift your body into fat burning mode
• Avoid overtraining or undertraining
• Measure how well you recover between sets
• Know if you’re burning ketones for energy
How to Calculate Your Target Heart Rate
Here’s the formula
220 minus your age equals your max heart rate
From there you can calculate your ideal heart rate zones based on your goal
Heart Rate Zones

Fat Burning Zone also known as the Ketone Zone is 50 to 70 percent of your max
Cardio Zone is 70 to 85 percent
Anaerobic Zone is 85 to 95 percent
Example If you’re 40 years old
220 minus 40 equals 180 max heart rate
Fat burning zone would be 90 to 126 beats per minute
Cardio zone would be 126 to 153 beats per minute
Anaerobic zone would be 153 to 171 beats per minute
The Fat Burning Zone and Ketones

This is where it gets real If your heart rate is in the 50 to 70 percent range your body is more likely to use stored fat and ketones for energy especially if you’re doing low carb or intermittent fasting
This is perfect for
• Burning stubborn fat
• Boosting metabolism
• Improving endurance
• Building lean muscle
You can hit this zone even during strength training especially when you’re doing supersets circuits or taking short breaks
How to Know You’re Using Ketones

You’re likely burning ketones if
• You haven’t eaten carbs in 12 to 16 hours
• Your heart rate stays in the 50 to 65 percent range
• You feel sharp and energized even without eating
• You’re not feeling hungry during your workout
Training in this zone while fasting is one of the most effective ways to melt fat
