HOW AND WHY SPIN STRONG IS SO EFFECTIVE

Introduction

Introducing Spin Strong Jump Rope Trainers, the revolutionary handheld, arm spin trainers that use air resistance just like a jump rope, for the same great exercise, but none of the difficulties.  Additional arm and leg exercises provide extensive strength and cardio exercise. While there are lots of new strength training products each year, there are few that provide something original or uniquely valuable. Spin Strong is the rare exception.

The specific details of how Spin Strong creates intense air resistance, the complex body mechanics involved and why this type of strength training is so valuable will be covered.


The Spin Strong Jump Rope Trainers

Spin Strong starts with the popular resistance training provided by a jump rope, which is air resistance created by circular arm movement. Jumping rope is excellent for cardio, and it is really good for strength conditioning, including for the upper body, even with just the one basic arm spinning exercise.

Spin Strong replaces the confining rope with a pair of fin-cords that provide freedom of movement. With little or no training you can jump rope using a wide variety of jumps. Some of the popular ones include jumping side to side, back to front, criss cross, jumping jack jumps and jumping rope backwards. You can add other leg exercises like lunges, squats, kicks and leg lifts. Many new arm exercises are available, including the Nine Key Exercise, which more highly engage the upper body for higher intensity.

The Nine Key Spin Strong Resistance Exercises

 

 

Spin Strong’s Innovative Design

Spin Strong consists of a pair of handle attached fin-cords. Each of which includes a seventeen inch spin cable and five (or six) Tri-Fin Air Resisters attached and which provide intense air resistance when spun in use. Each Tri-Fin Air Resister (or fin module) is made of flexible plastic. It has a hollow hub, and includes three fins that are symmetrically spaced around the hub and extended outward. The fin modules are free to rotate around the spin cable, but don’t. As the cables and attached fin modules are spun in hand, the force of air resistance is balanced on each side of the cable, holding it stable as it moves through and deflects the air, generating continuous air resistance.

Air Resistance and Circular Arm Movement

Air resistance opposes an object’s forward motion, even in the case of circular movement. Air resistance provides continuous and directly opposing force to an arm’s “forward” movement along the path of the circle.

Unlike traditional upper body strength training, air resistance combined with circular arm movement strengthens for movement in every direction. It produces extremely fast resistance training, which improves quickness and coordination, and it is continuous, which improves upper body endurance.

Air resistance is a function of speed and the size of the object moving through air (which determines the amount of air displacement). Spin Strong uses light and relatively small fin modules, but they are capable of being spun fast. So, they are highly effective at creating high intensity air resistance. The method and mechanism are so innovative, Spin Strong is patented.

Air resistance increases exponentially. For each doubling of speed, air resistance quadruples. It is not unusual to do 200+ circular arm movements per minute. As we will see later, circular arm movement is complex and each circle is equal to over eight sequential arm movements. So, this is a high number of arm movements in a short period of time, making Spin Strong very efficient.  Doing thousands of small resistance movements add up to significant and multidimensional strength training. This is a new and very beneficial type of strength and conditioning.

Spin Strong is not isometric exercise. There is significant movement occurring, even if it looks like small arm circles. Weight based circular arm resistance is much closer to isometric exercise, because spinning a weighted object creates an outwardly directed force, and you can basically hold your hand in one place to do complete those circles. Weight based circular training provides little resistance until you use a heavy weight which would be dangerous to spin.

  

The Forces Involved in Using Spin Strong

While air resistance is the primary force of Spin Strong training, other types of force are involved. Spin Strong trainers weigh only11 ounces, but this small amount of weight works with the air resistance to provide dynamic and intense resistance training.

The other type of force is from exercising using extended arms, which creates a lever effect (with the shoulder joint acting as the fulcrum), intensifying the resistance.

You can increase resistance by using larger arm circles by engaging the shoulder joint more. Also, configuring Spin Strong with an additional sixth set of air resisters (which can be purchased separately) significantly increases resistance.

The Spin Strong Approach to Jumping Rope

Spin Strong provides realistic jump rope exercise using a different formula for air resistance than a jump rope. When both are spun at the same speed, a jump rope moves through the air faster, because it is traveling around a much bigger circle each revolution. But Spin Strong trainers provide bigger objects moving through the air (and more air displacement). Spin Strong trainers have been sized to provide the normal amount of air resistance when used for jump rope exercise.

Complex Arm and Upper Body Movement

Spin Strong trainers use flexible fin-cords. So the only way to spin them is with a pulling motion. This whip-like action integrates strength, energy and movement from the upper body and sequentially transfers it through the shoulders, arms and hands.

This Spin Strong whip-like movement is very complex. It includes much of the upper body, the shoulder joint, the most complex circular joint in the human body, and which has a full range of 360 degree movement. It also includes the elbow joint and the wrist joint, which is also a circular joint with a full range of 360 degree movement.

Four Arm Movements in One

A circular movement of the arm at the shoulder join is called circumduction. It equals four sequential movements of flexion (up), abduction (out), extension (down) and Adduction (in). The wrist joint provides similar circumduction.

Spin Strong uses circumduction at the shoulder joint, including these four sequential movements, as well as at the wrist joint, including four similar sequential movements. And in between these two joints, Spin Strong uses the complex elbow with multiple joints for constantly flexing and rotating the arm, as well as turning the forearm with pronation and supination. The sum total of all these arm movements is conservatively ten sequential movements. This is incredibly complicated circular arm movement, especially at such fast speeds.

Strengthens Major Arm and Shoulder Muscles


Spin Strong movements engage and strengthen all the major muscles of the shoulders, arms and hands. They engage multiple muscle groups of the chest and upper back, and stabilize the core. The hands are gripping and spinning the Spin Strong trainers, which likewise engage the forearms. Biceps and triceps are engaged in elbow and shoulder movement.

Spin Strong arm training builds muscles for strength and speed and increases endurance. The many different arm spinning exercises provide unique training for arm movement in any direction, especially for movement of extended arms. No other exercise can duplicate this type of exercise, and it’s value will improve functional and sports related arm movements.
