Introducing the kBox Methods for Isometric Training

We are serious about methods for flywheel training, and we have often talked about eccentric training. Today, Fredrik Correa presents our new kBox methods for isometric training, a part of the growing knowledge base on our website about advanced flywheel training methodology.

Assisted IsometricsThe first sensation when going harder on the kBox is certainly most often the eccentric pull. “Oh no, it’s going to suck me down through that tiny hole!”. Many stick with this feeling and see the kBox as a tool for high eccentric loading.

They aren’t totally wrong. However, I believe the kBox is the best strength training tool in many aspects such as safety, affordability, mobility and the rather quick learning curve. I love the eccentrics but you shouldn’t miss out on the wide loading range the kBox offers!

Even though the eccentric contraction often precedes and determines the effectiveness in the following concentric contraction, in sports the other two phases are as important in building massive strength: the concentric and isometric contractions. Isometrics can be good in many situations like strengthening a sticking point, when preparing yourself for heavier lifts, or for potentation.

So let us give you an overview how the kBox can be tool for isometric training, pre-concentric isometric PAP and pure concentric training starting with:

I hope this will inspire you make other uses of the kBox, to even more realize the potential of a multi-exercise device for flywheel training. If you have any ideas on how you want us to elaborate on this matter, just let us know. We are doing this for your feedback.

Happy DOMS!
