INTRODUCTION
What is it? The kPulley is a compact exercise device used for
predominantly horizontal actions. It is a flywheel exercise
device and uses the moment of inertia to provide a high
and variable resistance in both the concentric and
eccentric* movements of the user.
*) concentric muscle action is when the muscle is being
shortened while an eccentric muscle action is when the
muscle is being elongated during action. In some literature,
concentric and eccentric is called positive (shortening)
and negative (lengthening) phase.
How does it work? The kPulley has a drive belt wound around a shaft located
in the back of the device. Different combinations of
flywheels are mounted on the end of the shaft, and you
can mount two flywheels up to 0.070 kgm2respectively
summing up to a total inertia of 0.140 kgm2 in total.
Using hand grips or an ankle cuff attached to the Pulley, the
User should then pull to accelerate the flywheel and then
resists to decelerate the flywheel as the belt winds in the
opposite direction.
Setting up the kPulley The kPulley must be fixed to a Sorinex®rack using the
attachment part and have the drive belt inserted before
being used.
Foot protection The foot protection piece must be assembled after
unpacking the kPulley. This is recommended highly in order
to protect against injury. To fix the protection piece slide
the hooks into the holes in the front and push down firmly.
The Flywheel We offer five different flywheels with inertia: 0.005, 0.010,
0.025, 0.050 and 0.070 kgm2. All flywheels from the kBox4
generation are compatible with all kPulley versions. The
maximum capacity the kPulley can hold at one time is two
flywheels. This allows for a range of inertia between 0.005
and 0.140 kgm2.Do not try to mount more than the
maximum capacity of flywheels.
Experimentation will determine which configuration is
required for your level of training. Mounting or changing
flywheels is done by releasing the Flywheel knob. To do so,
pull the knob on its side, remove the knob, change
flywheel(s) and securing them by pushing the Flywheel
knob back on until it makes a clicking noise.

FEATURES
Principle of the kPulley The kPulley is a ‘flywheel exercise device’. Which muscle is
being exercised depends on which exercise is being
performed.
The principle is that through muscle force, you accelerate
and decelerate a flywheel (or flywheels). Exercises with
high intensity and high forces stimulate muscles to
increase in size and the nervous system to increase
activation of the muscles. These effects together increase
strength over time, if the exercise is repeated regularly.
Resistance The resistance is variable and unlimited. The flywheel has a
specified inertia and there is no upper limit to how much
kinetic energy you can produce in the flywheel motion. You
can think of the flywheel as a weight that weighs more with
the more effort you put into lifting it. Resistance is variable,
so if you pull less the flywheel will resist less.
Every repetition in a maximal set is maximal instead of only
the last one which is the case with traditional weights. This
results in a higher training efficiency, earlier onset of
strength increase and also hypertrophy.
Eccentric Loading The kPulley provides for increased eccentric workloads.
The skeletal muscles can produce higher force in the
eccentric, or negative phase. This is difficult to take
advantage of with traditional weights, which always weigh
the same.
If you accelerate the flywheel during the concentric, or
pulling phase then decelerate in a short period of time,
you will have to produce a higher eccentric force. This will
be similar to lifting weights that would normally be too
heavy unless assisted by a training partner(s) but
executing the eccentric (lengthening) phase by yourself.

USAGE
Foot Placement Stand in front of the kPulley on the floor. Depending on
which exercise you wish to perform and the range of
motion needed, position yourself closer or further away
from the device to get to an appropriate range of motion
Range of motion Set range of motion by 1) positioning yourself closer or
further away from the beam or 2) adjust the drive belt
length at the top using the drive belt stop (see below).
Setting the height You can select at what height the belt should come out
from the kPulley. For horizontal actions, a perpendicular
angle to the kPulley / wall is recommended. Unlock the
attachment locks, move the adjustable pulley to desired
position and lock it in.

Setup Select desired inertia and accessory to use for the
exercise you want to perform. Connect accessory to the
pulley block by pulling the “Pull To Release”-tag on the snap
shackle, insert the accessory connecting point and close
the snap shackle.
Exercising Pull gently for 1-2 repetitions to assess that you have the
correct inertia and positioning and then increase to
desired exercise intensity. Avoid hitting the adjustable
pulley with the pulley block!
Overload Use a stronger movement pattern or your body weight to
accelerate in CON and absorb with the muscle you want
to overload in ECC.
Ex. Row - use lower back to accelerate and absorb with a
stiff back to put ECC load on upper back and arms.
Ex. Rotator cuff - step away from the device to accelerate
in CON and absorb in ECC in this position.

MAINTENANCE
Drive Belt Cautions The kPulley Drive Belt and its attachment to the shaft is the
most sensitive part of the kPulley2. Be attentive to wear
and check regularly.
Trim / replace When the Belt shows signs of wear and tear, trim the end
by cutting off the damaged area or replace it with an
original spare Drive Belt.
Trimming worn Belt If damage occurs close to the shaft, it is possible to cut off
the damaged end and reattach the new end.
Procedure
1. Remove shaft cover. Use 4 mm hex key from tool kit.
2. Unwind all of the belt from the shaft.
3. Use Pin Removal Tool to push the Belt through the shaft
and remove the Locking Pin.
exxentric.com/support 12
kPulley2, Sorinex

rack manual v1.3
4. Cut off the damaged Belt. Harden edge with a lighter.
6. Pull the Belt through the shaft from the side with the
more narrow groove. Fold Belt around Locking Pin and pull
the Belt and Pin into the wider groove in the shaft
7. The Belt automatically locks into the groove when you
pull it firmly. Make sure you can see the edge of the band
when it’s in place in the shaft (highlighted in third photo
below)
8. Put the shaft cover back and start training!
Note: If the lock pin is dropped inside the chassi, there is a
spare one in the tool kit. If both are lost, remove the chassi
from the beam and pick them up.
Replace Drive Belt completely Remove Belt from shaft as above, pull it out through the
shaft and through the pulley block and the sliding
pulley. Disconnect the Drive Belt from the belt stop.
Re-attach new Drive Belt in the belt stop and reverse the
procedure.

kMeter II
Overview kMeter II allows you to connect your smartphone or tablet
with your kBox or kPulley and get training feedback. All
kPulley versions have the kMeter II built-in as standard. It is
powered with two AA batteries.
SmartCoach Previous kMeter module version (wired) works with
SmartCoach system but to connect SmartCoach to kMeter
II you need a special version of kMeter II with a wire and this
needs to be specified when you order your kPulley (or kBox)
system.
How it works kMeter Module sends wireless data over Bluetooth to the
corresponding iOS or Android app. The kMeter App uses
rotational data and user-input of inertia to calculate and
present power in real-time and a set summary containing
average power for every rep, average power for set, peak
power in CON and ECC for every rep and for sets in total,
range of motion, force, number of reps, average. rep time
and energy expenditure. Users can input training data after
a completed set (exercise, comment and VAS 0-10 to be
used for pain or exertion for example). All data can be
stored in an in-app database for later view in the app or
exported to Excel.
kMeter II has a sample rate of 10000 Hz and receives 64
impulses per revolution of the flywheel. This means it can
accurately sample data up to rotational speeds of 155
revolutions/second..
