This MCP server provides specialized physiological tools to determine your optimal heart rate training zones. Using the scientifically recognized Karvonen method, you can calculate your Heart Rate Reserve (HRR) with calculate_heart_rate_reserve. The server also allows you to compute specific BPM boundaries for all five intensity levels using calculate_zone_ranges, and retrieve standard intensity descriptions via get_zone_definitions. Perfect for athletes looking to target specific metabolic responses like fat oxidation or anaerobic threshold improvement.

Calculate my heart rate zones. I am 30 years old and my resting heart rate is 60 BPM.

Based on your age of 30 and RHR of 60, your training zones are: Zone 1 (120-132 BPM), Zone 2 (132-144 BPM), Zone 3 (144-156 BPM), Zone 4 (156-168 BPM), and Zone 5 (168-180 BPM).

What is my Heart Rate Reserve?

Please provide your age and resting heart rate so I can use `calculate_heart_rate_reserve` to find your value.

Show me the definitions for all heart rate zones.

Using `get_zone_definitions`, I can confirm that Zone 1 is very light (50-60%), Zone 2 is light (60-70%), Zone 3 is moderate (70-80%), Zone 4 is hard (80-90%), and Zone 5 is maximum intensity (90-100%) of your HRR.

The Karvonen formula calculates Target Heart Rate (THR) by using your Heart Rate Reserve (HRR), which accounts for both your maximum heart rate and resting heart rate to provide a more personalized training intensity.
