INTRODUCTION
What is it? The kPulley2 is a self-contained, 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 kPulley2 has a drive belt wound around a shaft and
different combinations of flywheels are mounted on the
end of the shaft.
Using hand grips or an ankle cuff attached to the Pulley, the
User then pulls to accelerate the flywheel and then resists
to decelerate the flywheel as the belt winds in the opposite
direction.
Setting up the kPulley2 The kPulley2 must be firmly fixed to a wall or column by
being screwed to the wall using the designated (round)
holes in the center of the beam or fixed by a strong belt in
the bent metal pieces on the back of the beam.
Foot protection The foot protection must be assembled after unpacking
the kPulley2. This is recommended highly in order to protect
against injury.

kPulley2 manual v 1.0
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 the kPulley2. The maximum
capacity the kPulley2 can hold at one time is two. 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 black knob on its side, remove the nut, change
flywheel(s) and secure them by pushing the Flywheel knob
back on until it makes a clicking noise.

kPulley2 manual v 1.0
FEATURES
Principle of the kPulley The kPulley2 is a ‘flywheel multi-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 kPulley2 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 amount 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 kPulley2 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 Can be set by positioning yourself closer or further away
from the beam or change the length of the drive belt by:
A) adjusting the height of the sliding belt stop (pic 1) or
B) adjusting the amount of excess belt coming out of the
belt stop (pic 2).
exxentric.com/support 13
kPulley2 manual v 1.0
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. Pull knob to
release the lock. Hold the sliding part in place and adjust
the height, let go of the knob and let it click-in and lock the
position.
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.
Overload Methods to overload the eccentric phase:
#1 Use a stronger movement pattern or your body weight
to accelerate in CON and absorb with the muscle you
want to overload in ECC.
#2 Partial ROM in ECC. By either absorbing all energy early
or late in ECC this part of the ROM is overloaded.
#3 Have a spotter adding energy in CON to subsequently
overload ECC for user.

MAINTENANCE
Drive Belt Cautions The kPulley Drive Belt and its attachment to the shaft is the
most sensitive part of the kPulley. 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. Hang shaft cover on height adjustment pulley hook
-
3. Unwind all of the belt from the shaft.
4. Use Pin Removal Tool to push the Belt through the shaft
and remove the Locking Pin.
5. Cut off the damaged Belt. Harden edge with a lighter.
exxentric.com/support 16
kPulley2 manual v 1.0
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
Overview kMeter allows you to connect your smartphone or tablet
with your kBox or kPulley and get training feedback. The
kPulley2 has the kMeter II built-in as standard. It is powered
with two AA batteries and located under the base unit
cover plate.
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 kPulley2 (or
kBox) system.
How it works kMeter 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..
