Flywheel training also offers safe and easy eccentric overload offering the user higher gains in muscle mass and strength. The kBox4 Lite comes as a starter system, however, a full range of attachments, harnesses, flywheels are available to customise it to your requirements.
There is no upper limit to how much kinetic energy you can produce, in the flywheel motion. This means that you can always use a higher force and accelerate the flywheel more. Resistance is variable in that if you pull less the flywheel will resist less. Therefore, the kBox4 is suitable for both resistance training and rehabilitation.
With FWEDs, every repetition is maximal, with both a higher force early in the set and lower in the end, making the exercise much more efficient. This is why flywheel training gives a hypertrophic response earlier in the training regimen than traditional weights.
You can also attach any handle or grip and do many upper body pulling and pushing exercises for arms, shoulders, upper and lower back.
