The Candle Burning Guide - Center Burning Candles. Certain candles are designed to burn down the middle for different reasons, or a combination of different reasons. Candles with a unique finish, or unique burning characteristic, may burn down the middle in order to position the flame inside of the candle and illuminate from the inside out.
To find your maximum heart rate, subtract your age from 220. For example, if you are 40 years old, your maximum heart rate is 180 (that is, 220 - 40 = 180). Multiplying this by 50 percent and then 85 percent results in your target heart rate range of 90 to 153 beats per minute.
The simplest way to compute your target heart rate is to subtract your age from 220âthatâs your maximum heart rateâand then calculate 60 and 80 percent of that number. For example, if you are 50, your maximum heart rate is 220 minus 50, or 170. Then multiply 170 by 0.6 (for the low end) and by 0.8 (for the high end), which gives a range of 102 to 136. Your heart rate should fall between these two numbers while you exercise.
