Stair
Machines
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.

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.
