PLEASE REMEMBER!
➢Isometric Strength Training (IST) can be strenuous. Please consult your Healthcare
Practitioner before embarking upon any new training regime.
➢IST can involve high levels of force. Always warm-up your muscles and joints
thoroughly before serious practice.
➢The Isochain handle is constructed from durable materials, but it still contains
electronics; always set the handle down carefully. Never drop the Isochain handle.
➢The Isochain is manufactured to accommodate 1000 lbs of resistance. Do not use
more than this. If you find your front squat or deadlift creeping above this weight,
switch to more difficult exercises (e.g., split squat, Bulgarian split squat, iso-pistol,
hack squat, single-leg deadlift, etc).
When constructing your Isochain, it is
important to attach the components in
the correct order:
The handle’s loading ring (1) should
attached to a screw-lock carabiner (2).
This top carabiner should attach to the
revolving pin (3). This component allows
the chain to swivel, and protects the
loading ring from torque under high loads.
The revolving pin attaches to a second
screw-lock carabiner (4).
The second screw-lock carabiner attaches
to the top of the chain (5).
The chain attaches to a snap-hook
carabiner (6). This is the carabiner you
will remove and reattach when adjusting
the chain length during drills—there is no
need to ever remove the top, screw-lock
carabiners, unless you are dismantling the
device.
The snap-hook carabiner attaches to the
heavy-duty spring (7), which attaches to
the baseplate (8).

When you need to adjust the length of
your chain for a new drill, always use the
lowest, snap-hook carabiner. This will
save you lifting excess chain—any slack
chain will be attached to the bottom
carabiner, not the handle.
Lay down the handle carefully, and
disconnect the chain from the lower
carabiner. The chain is now loose.
Pick up the handle—the chain now being
unattached to the spring—and raise it to
the height you want for the exercise—for
example, sternum height. Look down, and
identify which chain link will be a few
inches (spring plus carabiner length)
above the baseplate (this can be an
approximate). Keep an eye on this area of
chain.
Kneel down again, and attach that area of
chain to the lower carabiner.
Your bar will now be at the desired height.
After a while, you won’t even need to
rehearse the drills with the chain
unattached to the spring—you’ll
instinctively know the height the handle
needs to be for various drills.

ISOCHAIN MODES
Sidebar letters
Battery level

FEEDBACK MODE: Tells you weight being lifted in real time
1. Feedback Mode is the Isochain’s default mode, when the device is turned on. When
Feedback Mode is activated, there is no sidebar letter on the display.
2. Whenever you push or pull the handle, the digital console displays the forces being
used in real time. (The speaker and timer do not function.)
LOAD MODE: Tells you when you reach a Target Load during an iso-hold
1. To activate Load Mode, press the key. The sidebar letter on the display will
read “L” when Load Mode is activated.
2. Use the Up/Down keys to select a Target Load (10-999 lbs).
3. The speaker will now bleep every second the Target Load is maintained or exceeded
during an iso-hold.
TIMED MODE: Tells you when you reach a Target Time for an iso-hold
1. To activate Timed Mode, press the key. The sidebar letter on the display will
read “T” when Timed Mode is activated.
2. To set the Target Time, hold the key for 2 seconds.
3. Use the Up/Down keys to select Target Time in seconds (2-999 seconds).
4. Once the time is set (stops flashing), use the Up/Down keys to set Target Load.
5. The speaker will now bleep every second the Target Load is maintained (or
exceeded) during an iso-hold, for the amount of time set in Step 3. The final bleep
will last two seconds, to let you know the Target Time is up.
MAX MODE: Tells you the maximum weight you lifted during an iso-hold
1. To activate Max Mode, press the key following an iso-hold (you can be in any
other mode when you do this). The sidebar letter on the display will read “M” when
Max Mode is activated.
2. The display will show the highest force level (as weight) achieved since the mode
was last changed.
AVERAGE MODE: Tells you the average weight you lifted during an iso-hold
1. To activate Average Mode, press the key following an iso-hold (you can be in
any other mode when you do this). The sidebar letter on the display will read “A”
when Max Mode is activated.
2. The display will show the average force level (as weight) achieved since the mode
was last changed.

Warm-up well before each session, and break into your training gradually.
PROGRAM A: MUSCLE-BUILDING (Load Mode)
Set the Target Load on each drill to a weight you can comfortably hold for around 20
seconds.
1. Deadlift 3 holds of 20 seconds
2. Shoulder press 3 holds of 20 seconds 3 SESSIONS PER WEEK
3. Bent row 3 holds of 20 seconds
4. Biceps curl 3 holds of 20 seconds
-When you can reach 20 seconds on each iso-hold, increase the Target Load by 10%.
PROGRAM B: STRENGTH & SIZE (Timed Mode)
Set the Target Load to a weight you can comfortably hold for around 10 seconds; set
the Target Time to 6 seconds.
1. Deadlift 6 holds of 6 seconds
2. Front squat 6 holds of 6 seconds
3. Bent row 6 holds of 6 seconds 3 SESSIONS PER WEEK
4. Shoulder press 6 holds of 6 seconds
5. Curl 6 holds of 6 seconds
-When you can perform all 6 reps for 6 seconds, increase the Target Load by 10%.
PROGRAM C: PURE STRENGTH (Max Mode)
Perform your drills in Feedback Mode (default setting). Don’t count the timing of your
holds—just pull/push for a few seconds until you feel you’ve hit your limit.
1. Deadlift 10 holds 3-4 SESSIONS PER WEEK
2. Shoulder press 10 holds
-Note your max weight on every hold, and try to improve them over time.
PROGRAM D: MUSCULAR ENDURANCE (Average Mode)
Perform your drills in Feedback Mode (default setting). Use a clock or an app alarm to
time your holds.
1. Front squat 4 holds of 100 seconds
2. Shoulder press 4 holds of 100 seconds 2-3 SESSIONS PER WEEK
3. Bent row 4 holds of 100 seconds
4. Clean pull 4 holds of 50 seconds
-Note your average weight after every hold, and try to improve it over time.
