Training Intensity Calculator (based on % of MHR or 1RM)

This tool helps you determine the correct intensity for your workouts.

For cardiovascular exercise. Enter your age to estimate your Max Heart Rate (MHR), or enter a known MHR if you have one. Then, input your desired intensity (e.g., 70%) to find your target heart rate in beats per minute (BPM).

For weightlifting. Enter the maximum weight you can lift for one repetition (your 1RM). Then, input your desired intensity (e.g., 85%) to find the target weight for your working sets.
