FEATURES OF THE KBOX
Principle of the kBox The kBox is a flywheel exercise device, often referred to as an FWED.
What muscle is being exercised depends on which exercise is being
performed.
The principle is through muscle force you accelerate and decelerate a
flywheel (or flywheels). Repeated exercises with high intensity
produces high forces that stimulate muscles to hypertrophy and
increase activation of the nervous system. These effects together
increase strength over time if the exercise is repeated regularly.
Resistance The resistance is variable and unlimited . The flywheel has 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 which
weighs more the more effort you put into lifting it. Resistance is
variable in that if you pull less the flywheel will resist less.
Every repetition in maximal set is maximal instead of only the last one
which is the case with traditional weights. This results in a higher
training efficiency and earlier onset of strength increase and
hypertrophy
Eccentric Loading The kBox 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 would be similar to lifting a too-
heavy weight with help from training partners but do the eccentric
phase by yourself.
Mobility The kBox is mobile in comparison to traditional weights. Squatting with
the kBox is equivalent to traditional squats which would require a
barbell, weights up to 500 lb. for a strong lifter which is practically
impossible to carry around. In addition you’d need rubber
note that......
the higher efficiency of the kBox may require longer
periods of rest between sets and training days
to fully recover.
