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 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.
