Frequently asked questions

What is closed chain exercise?

Closed kinetic chain exercise takes place with either the upper or lower extremity fixed on an immovable object. The associated muscles contract in an effort to move this object, unable to move the object, the muscular contraction causes motion in the opposite direction moving the bodies center of mass instead. This is how our lower extremities function when we move around our environment and this type of contraction is needed in the upper extremity exercise to decrease stress on the shoulder joint.

What does CKC stand for?

Closed Kinetic Chain

Why should I care about training functionally?

Functional training increases the efficacy of our physiology and ultimately helps us move better for a longer period of time. In short, functional training has the potential to reduce our propensity to injury, affect how we feel and the improve the quality of our longevity as we age.

Why is training the arms in a closed chain important?

The shoulder joint is anatomically unstable in an open chain. Even though humanity has evolved from using the upper extremities as legs, they are not designed to function solely in an open chain. They are designed to utilize the compressive forces of gravity to assist with joint stabilization. The shoulder has a cuff of musculature (the rotator cuff) to assist in this stabilization. When the compressive forces provided by gravity are utilized in closed chain exercise there is less need for the rotator cuff musculature to stabilize the shoulder joint. On the other hand, motion in an open chain, especially with load, places a great deal of stress on this rotator cuff musculature. Over time the rotator cuff wears out. As a result of this disruption the rotator cuff is a major cause of pain and disability in modern life.

Can I get a challenging workout?

Yes! The CKC Trainer allows all users to follow the principles of a properly designed exercise program, thus you will see the same results as far as body composition changes as in other forms of resistance training exercise. In fact, the CKC Trainer can add resistance to your functional workout for advanced users or it can offload body weight for those just starting a functional training program, so it is the optimal functional training option for all populations.

How long do the resistance bands last?

This, of course, depends on use. If used properly the bands can last for years. CKC fitness recommends replacing the bands every year as the bands will lose their elasticity in time.

Is it difficult to set up the band holders for each exercise?

No, not at all. The exercise page describes the set ups of each exercise in detail, and since most sessions will consist of similar exercises, you will quickly become familiar with band hanger placement. After just a few times of adjusting the band holders it will become second nature to you.

Are workouts fun?

Absolutely! The CKC Trainer will make you feel like a kid at the playground again. You will not dread your resistance training workouts anymore. You will look forward to challenging your body in the way it was designed to be challenged.

How the the CKC Trainer different from anything else on the market?

The CKC Trainer will allow you to do exercises you would otherwise be unable to do. It is empowering to be able to do something you would otherwise be unable to do. From the ability to do a standard pushup to being able to do one arm pull ups, the CKC Trainer provides cutting edge training exercises that will maximize your results and overall fitness.

What is power?

Power is the marriage of strength and speed. Power is defined as work / time. When a muscle can produce more force and contract faster, the time needed to move an object from point ‘a’ to point ‘b’ decreases and the neuromuscular unit becomes more powerful. Power is an important aspect in the human motion and sports performance. The CKC Trainer allows you to do over-speed training, and not just with your lower body but with your upper body as well.

Why is training on one leg important?

We do not hop like bunnies. Human motion is really a process of generating force and accepting force from one lower extremity limb to another. It is like a series of one legged squats alternating from one leg to the other. If one limb is stronger than the other then it has a hard time keeping up with the forces generated by the other. Over time injury occurs. We are only as strong as our weakest link.

Why should the spine not be excessively loaded when doing resisted exercises?

The human spine is not designed to bear excessive amounts of weight. It was designed to be a bridge between our arms and legs. Loading the spine in excessive ways and using it in ways it has not evolved to tolerate will cause spinal joint dysfunction and derangement. Single limb lower extremity resisted training is functional and increases the stress on the exercising limb without unneeded load on the spine.
