Leg SpeedChain®

The Leg SpeedChain® is a tremendous training tool for increasing lower body strength, explosiveness, balance/symmetry, and mobility. It is a training aid that builds power in the lower half by utilizing multiple planes of movement through variable resistance. The device causes the body to adapt to ever-changing loads, lending itself to differential learning ❓.

The Leg SpeedChain® allows the body to self-organize and discover efficient movement patterns using the Dynamic Systems Theory ❓, reinforcing the importance of coordination versus isolated strength. The exercises performed with the device are at high intensity, for short durations, utilizing the body's ATP energy system. It is a tool for training basic high-velocity movement patterns, with balance and proprioception ❓ that can lead to faster sprint times, further/higher jumps, and ultimately greater overall power output from the lower body. The Leg SpeedChain® has the freedom to accommodate many different stride lengths and lower half mechanics.

Training with the Leg SpeedChain® offers the athlete an opportunity to train joint movement, muscle action, and energy production that can match virtually any sports-related movement. It can be used on many different surfaces, environments, and conditions. Each variation provides cues that excite the tactile, auditory, and visual senses reducing exercise monotony and boredom that can lead to reduced motivation.

The Leg SpeedChain® is a custom constructed metal chain attached to a sturdy metal foot bracket with links that increase in size and weight as the distance from the bracket increases. This design allows initial movements to be easier because smaller/lighter chain links move initially, with the movement pattern becoming increasingly difficult as the heavier distal chain links are involved. This varying resistance provides an excellent underload/overload experience with movements that are general to lower body development.

The Leg SpeedChain® may be purchased as a stand-alone training device with an included Universal SpeedChain® Segment, or, purchased as an accessory to be used with one (or two) Universal SpeedChain® segment from other devices. Available in two sizes, the Leg SpeedChain® can be used on either foot and is generally fitted based on shoe sizes: Medium - Shoe Size 7-12; Large - Shoe Size 12-17.

Muscularly mature athletes considered strong for their peer group, and athletes 6'4" and taller, should consider adding extensions to their selection. Each model may have up to two SpeedChain® Extensions added as necessary when the lower half speed and strength increases. If there are questions about model sizing it is recommended to undersize the model size and make adjustments with extensions. Always waggle the SpeedChain® through the anticipated full range of motion before beginning exercise; chain ends should never be allowed to come off the ground/floor or gather around the feet during exercises.

The Leg SpeedChain® delivers resistance light enough to permit high acceleration and resistance heavy enough to increase strength. This is accomplished through variable weight loads, with different phases of a movement being weighted differently; the variable resistance challenges the athlete to move the volume of the chain according to their strength. The SpeedChain® trains and supplies a means to develop stronger movements and joint actions using the larger chain links higher weights to train at higher levels of force.

The Leg SpeedChain®, also sometimes called the 'Kicking Chain' is an outstanding general training implement that can be purchased as a stand-alone training tool consisting of a foot harness, One Universal SpeedChain® Segment, and Chain Carrier. For an enhanced training experience, consider adding the TorsoBurner® for a full-body experience. Either or both of the Universal SpeedChain® Segments used with the TorsoBurner® can be used alternately with Leg SpeedChain® as well as the Golf or Tennis SpeedChain® Sport Specific Quick-link Attachments. All components are available and can be purchased individually. Instructions for use are not included.
