The
stair machine mimics the action
of climbing stairs with varying
degrees of success. There
are a number of different
stair climbers available.
- The
first and worst
are the little hydraulic
floor models that
have a four inch
range of motion
with one pedal being
pushed up as the
other goes down.
Don't bother with
these ones.
- The
next is the larger,
health-club version
with the same mechanics
of one pedal going
up as the other
goes down. This
is somewhat better
as the range of
motion is greater.
The best version
has independently
moving pedals. This
better simulates
actual stair climbing
because you must
actually raise your
leg instead of having
the machine force
it back up for you.
- The
last type of stair
machine is the treadmill
type where a set
of stairs continuously
rotates around.
This is also known
as a Stepmill. This
most closely approximates
actual stair climbing,
as you must constantly
step up. Be sure
to push off forcefully,
otherwise you will
run into the same
problem as in the
treadmill where
the backward work
is done for you.

General Stair
Machine Information
The
stair climber is a low impact
machine that can be useful
for all levels of fitness.
 |
- They
only apply force at
about 1.2 times your
bodyweight, which
is comparable to walking.
Actual stairs apply
forces of twice your
bodyweight on the
way up and up to seven
times on the way down.
- Stair
machines are not bad
for your knees. Those
with back problems
should be careful
not to lean over excessively.
- A
potential complaint
about stair machines
is foot numbness.
This comes from continuous
pressure on the feet
for extended periods
of time. Lift your
feet off every now
and then to help circulation.
- Do
not lean on the rails
while stepping. Many
trainers tend to lock
their arms and support
their body on the
railings at arm’s
length. This decreases
the effectiveness
of the exercise considerably,
reducing it to a short
pumping motion.

What to Look For When Buying
a Stair Machine
Here
are some to points to consider
if you are looking at purchasing
a stair-machine.
- Look
for one that is cable
or chain driven. This
will increase its
longevity.
- A
comfortable minimum
stepping speed is
an important feature
for beginners or those
who are not in good
shape.
- It
should be stable without
any wobble.
- A
good machine will
have hinges on the
pedals to allow your
feet to remain parallel
while stepping. Slanting,
fixed pedals can strain
ankles.
