Dynamic Strengthening

TRI-STRETCH® allows for just the right amount of instability for dynamic balance and strength training of the lower extremity and core. Allow TRI-STRETCH® to add instability in two unique ways:

  • Providing a tri-planar unstable surface with end points to prevent excessive instability and loss of balance -which allows safe use of additional resistance such as medicine balls , elastic bands and free weights without risking injury from too much instability AND
  • ability to challenge the lower extremity and core in the sagittal, frontal and transverse planes.

Conventional balance training often consists of numerous random exercises, increasing in perceived difficulty. Does utilizing a multi-directional balance board offer the ability to progress balance and strength training along an organized systematic path of least to most difficult?

Consider an approach based on the biomechanics of the movement of joints and mechanical advantage or disadvantage of the musculature rather than on general balance training of miscellaneous exercises. Application of knowledge of muscle origin, insertion, function and biomechanical science allows the trainer to progressively challenge the athlete. Use of a tri-planar rather than a multi-directional balance board can assist the trainer and athlete in this endeavor.

TRI-STRETCH® Dynamic Strength Training

Utilizing TRI-STRETCH® in its “normal” position allows the lower leg muscles to load in the sagittal plane while still allowing dynamic instability in the frontal and transverse planes. TRI-STRETCH® also allows for control of the instability secondary to the frontal plane rockers providing a stable endpoint. This allows for higher intensity medicine ball exercises to be successfully performed without loss of balance.

TRI-STRETCH® Dynamic Strengthening and Improving Balance By placing the TRI-STRETCH® device backwards, in a more plantar flexed position, the ability of the calf to decelerate movement of the exercise selected will be lessened. This position therefore calls on the more proximal muscles of the hip and core to control the motion of the exercise selected.

Application of functional biomechanics to the exercises that the athlete performs and to the equipment that is utilized provides for a much more systematic progression of strength and balance training. Utilization of a tri-planar device such as the TRI-STRETCH® is a tool that allows the trainer to design multiple new exercises in a methodical progression that are just not possible without such a tool.

Each TRI-STRETCH® device comes shipped with a free instructional DVD on dynamic strength and balance training for the lower extremity and core.
