What is your target heart rate?
disa [49]

Answer:

с.  60-80% of your maximum heart rate

Explanation:

The "target heart rate" is very important when you want to know how to do your exercise properly <em>without straining your body</em> <em>or relaxing too much. </em>In order to do this, you have to get your<em> "maximum heart rate"</em> first by subtracting your age from 220. The difference will be multiplied by 60% to 85%, depending on the exertion level that you want.

For example, your age is<em> 20</em>. You have to<em> subtract 20 from 220 </em>and that will give you a maximum heart rate of <em>200 beats per minute (bpm).</em> If you want a 60% exertion level, your target heart rate is 120 bpm (200 x 60%).

How do you count you heart beat
Ksivusya [100]

Answer:

see below

Explanation:

Do you mean beats per minute (BPM)?  To find that, take your index & middle fingers and place them together on your neck or wrist where you feel your heartbeat.  Take a timer or stopwatch and count how many beats you feel in 15 seconds.  Multiply this number by 4 to get your BPM (alternatively, you could also count for 30 seconds and multiply by two, or for the full minute, but 15 seconds is a lot faster and easier).  If you need a resting BPM, either take it when you wake up in the morning (most accurate), or rest for a while.

I hope this helps!
