Treadmills
: It's a fact. Treadmills burn more calories than
any other piece of fitness equipment. In test
after test, treadmills consistently burn more
calories than steppers, rowers and bikes. There
simply isn't a more effective cardiovascular workout.
Besides high marks in the calorie-burning column,
the healthy benefits of walking and running are
well documented as well.
When
buying a treadmill, here are some things to keep
in mind: Motor: The continuous-duty rating is
the motor's true continuous horsepower, not just
it's "peak" horsepower. So a 2.0 continuous-duty
HP motor is actually more powerful than a 2.0
HP motor not rated as continuous duty. For good
wear, Look for a motor with at least 1.5 continuous-duty
HP. Most home units are DC. Some commercial treadmills
are AC, which tend to be noisier and require a
dedicated power line. Speed: Most treadmills run
from 0 to 10 mph. A safe starting speed is always
an important safety feature. Treadmills designed
for more serious jogging or running go up to 12mph.
Some offer one-touch speed buttons to adjust speed
quickly and easily. Belt and Deck: Be sure the
length of the treadbelt is long enough for your
longest stride. The width of the belt should be
at least 16", although wider belts allow
for more comfortable strides. Likewise, longer
decks allow for a more comfortable stride. Two-ply
belts are stronger and less likely to curl at
the sides. Quality decks shouldn't need much maintenance
and operate at low temperatures. Impact Absorption:
Treadmills usually absorb some of the force from
the impact of your feet. Some use cushioning under
the belt, others have cushioning in the belt itself.
Some even offer electronic adjustable cushioning.
The lower the impact, the better. Incline: The
incline can range from 0% to about 15%. A wider
range is the best choice.

The
most high-tech treadmills offer incline that adjusts
according to the exerciser's heart rate. Others
have automatic electronic incline with the push
of a button. The electronic incline should not
be noisy or cause trembling. The least favorable
are those that require manual adjustment before
starting your workout. Control Panels: Electronic
feedback displays of speed, time, and distance
are generally standard on most treadmills. Some
also display calories burned, heart rate, incline
or workout history. Most treadmills offer preset
and/or custom programs you can design yourself.
Control panels range from a simple display to
fully programmable consoles with high-tech features,
such as the ability to run programs from the Internet.
Price
is influenced by the control panel options, so
purchase only what you will regularly use.
Heart
Rate Monitors: Many treadmills include some type
of electronic heart-rate monitor that enables
the user to stay in his target heart rate without
having to stop and manually take a pulse.
Chest-strap
monitors tend to be the most accurate. Thumb pulse,
ear clip and other strap methods are also available,
but less precise. Frame: High alloy, welded steel
with a protective coating to avoid rust is the
way to go. Avoid weaker materials and bolted frames.
Hand Rails: Some treadmills are designed with
a handlebar in front, some with side rails. The
location is a matter of preference.
