Peter's Principles - Exercise

Determining Training Intensity

1. Maximal heart rate = 220-age (MHR).
2. Check your resting heart rate (RHR).
3. Determine your heart rate reserve (HRR) by subtracting your resting heart rate from your maximal heart rate.
4. To calculate your training intensity at 70% multiply your heart rate reserve by 70%, then add your resting heart rate to these figures.

EXAMPLE:
• 220-40 year old person = max 180 (BPM);
• 40 year old person's resting heart rate is 68;
• heart rate reserve: 180 - 68 = 112 beats per minute;
• 70% of Training Intensity = (112 x .70) + 68 = 146 beats per minute; 146 beats per minute is your training zone @ 70%
