Using the Harness
Attach the harness to the pulley block with the harness
ends turned inwards (red double-stitched sides towards
each other).
Be sure the harness fits well and is not too loose (various sizes
are available). The straps shouldn’t slip down over the shoulders
and the horizontal strap should go around your lower back. The
horizontal strap should be tightened with the buckle at the front.
Use the red drive belt length adjustment button to set the belt
length to allow the belt to fully reach the upper end of the exercise
movement.
For beginners and rehab patients doing lower body exercises,
the top position should be just before all active joints are fully
extended.
For experienced users, there can be some slack in the
top position to minimize strain on the belt and hook at the reversal
point.
Remember not to stop the movement in an extended
position
when the flywheel is spinning, as this will put strain on your
joints if hyperextended.
Bend your knees slightly and take up the slack in the belt using
your hand to rotate the flywheel and rewind some of the belt. Next,
accelerate the flywheel by starting the exercise at a lower intensity.
Accelerate the flywheel at every repetition. After two to four
repetitions you should have reached your desired training intensity.
Perform your training set, usually 6-12 repetitions at desired
intensity.
Decelerate the flywheel on the way down and stop at the bottom.
Slowly return to your start position and
let the flywheel stop
completely
. Detach the harness, step off the platform and prepare
yourself for the next set. Make sure you get an adequate amount of
rest between sets.
