Training levels.
Here is how to calculate your training levels:
Take 220 (226 if you are a woman).
Subtract your age.
Multiply the result by 65%, 75%, 85% and 92%.
For example, I'm a 44 year-old man:
220 - 44 = 176.
176 x 65% = 114 which is the warm-up range.
176 x 75% = 132 which is the best aerobic fat-burning range.
176 x 85% = 150 which is the start of the strength building range.
176 x 92% = 162 which is the recommended maximum heart rate you should not exceed during a work-out.
Theory is that if you train at a sustained rate of greater than 85% you risk muscle injury and heart failure.
