At the Heart of
Fitness

There’s more to attaining optimum fitness than just
exercising. In fact, to get an effective workout many
things must be considered. One of the most important
factors is your heart rate.
Heart rate is the number of times your heart beats per
minute. Reach what’s called your Target Heart Rate and
the body becomes a calorie burning machine. Miss it and
your workout may have been all for naught.
Proper heart rate is so significant to fitness that
trainers monitor it when helping clients achieve their
fitness goals. It is a gauge of the body’s
cardiovascular level.
Much like how a car isn’t fully efficient until the
engine has warmed up; your workout hasn’t fully begun
until you’ve reached your target heart rate.
When at your target range, you get maximum benefit from
your workout. Your body is in fat burning mode. In this
zone you are effectively working out. Outside of it you
are wasting your time.

So
how do you calculate your target heart rate? It varies
by age. But generally speaking, a person’s Target Heart
Rate is: 220 minus their age multiplied by .75 - or
multiplied by .85 for increased intensity.

220 minus your Age, multiplied by .75 = Target Heart Rate
Innovative devices, such as the
MIO heart rate watch, make monitoring heart rate
thresholds easy. Calculations can be read by
merely placing two fingers on the bezel.
You can also monitor your heart rate manually. Place
your index and middle fingers on your wrist then count
the pulses for 30 seconds. Multiply that number by 2.
This yields your current heart rate.
Once you know your Target Heart rate you know how to be
successful in working out. Exercise lightly until you
reach your Target Zone. Once there, have a
calorie-burning party. Exercise with results.
The 3 Types of Heart Rates
• Resting: heart beats per minute when not exerting
oneself. Rate varies by person. Can be 40 Beats per
Minute (BPM), or as high as 100 BPM. Averages 70 BPM for
men and 75 BPM for women.
• Exercise: increased heart rate from sustained physical
activity. Also called the target heart rate range
• Maximum: rate at which the heart beats at 100%
exertion. Only work at maximum heart rate under the
supervision. Nears Anaerobic Threshold where the body is
essentially working out without oxygen. Threshold
depends on fitness level and age. Anaerobic threshold
can be damaging.
Possible side effects of going over your maximum heart
rate:
• Exhaustion
• The body stops burning fat
• Lactic acid builds up causing you to hyperventilate -
seeking more oxygen to remove the acid |
