Vigorous Training Heart Rate for Age 25, Resting HR 55 bpm
A 25-year-old with a resting HR of 55 bpm has a vigorous-intensity target heart rate of approximately 158–174 bpm.
How to use this tool
- Enter your age to estimate maximum heart rate.
- Enter your resting heart rate in bpm.
- Select the training intensity.
- Read your target heart rate and heart-rate reserve.
Calculate the vigorous-intensity training heart rate zone for a fit 25-year-old using heart rate reserve.
Frequently asked questions
- Why use heart-rate reserve instead of percent of max?
- HRR includes your resting heart rate, so it adjusts for fitness. Two people the same age but with different resting rates get different, more appropriate targets at the same intensity.
- How accurate is 220 minus age?
- It is a rough estimate of maximum heart rate with a spread of about 10–12 bpm between individuals. A measured maximum from a stress or field test is more accurate.
- Do beta-blockers affect the target?
- Yes. Beta-blockers and some other medications lower heart rate, so formula-based targets can overshoot what is achievable; targets should be individualised in that case.
