kPulley2 manual v 1.3
Introduction
Setting Up the kPulley
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.
The Flywhe
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 1.3
Features
Principle of the kPulley
The kPulley 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 if you put more effort 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.
Note that:
The potentially higher exertion on the kPulley
may lead to need for longer resting periods
between sessions to fully recover.
Exxentric 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
lifting phase and then decelerate in a shorter 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.
Check Training Guide for more information on eccentric
overload.
exxentric.com/support 10
kPulley2 manual v 1.3
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).
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.
exxentric.com/support 11
kPulley2 manual v 1.3
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.
kPulley2
Attachment Kit
To attach the kPulley2 to a pole or a rack, use the
brackets on the back of the beam and our
kPulley2 Attachment Kit.
Make sure to use at least three straps; one at the top, one at
the bottom and one in the middle of the beam.
Attention! Do not leave or permanently mount
kPulley2 outside!

kPulley Maintenance
Drive Belt Cautions
The Drive Belt and its attachment to the shaft
(axle) is the most sensitive part of the kPulley.
Be attentive to wear and check regularly.
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
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.
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. and use Pin Removal Tool
to push the belt through the shaft and remove the locking pin.

kPulley2 manual v 1.3
Trimming worn Belt
(cont.)
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.
5. 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).
6. Put the shaft cover back on 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.
Shaft Maintenance
Put WD40 (or similar) to the shaft within 8 weeks of receiving
your kPulley and then once every 6 months. The frequency of
applying rust protection will increase if you have your kPulley in
a more humid environment.

kMeter
Overview
kMeter Module allows you to connect your
smartphone or tablet with your kBox 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
kMeter module (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 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 a wide range of metrics. 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 10.000 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.
Manual
For info on how to connect and operate the kMeter module and
app, see kMeter manual. For information about the metrics and their
precision, check exxentric.com/kmeter-manual
