Techniques & Methods


Functional Range Conditioning (FRC) is a human movement optimization system that is based on scientific principles and research. It aims to improve mobility, increase joint strength and optimize body awareness allowing you perform your best at whatever sport or activity you may take part in.

At Perfect Stride we use FRC principles to help improve your usable range of motion, promote healthy and resilient joints and thus reduce your likelihood for injury. We work to increase your mobility and also improve your resiliency within all of these ranges of motion so that you can be prepared for whatever movement demands that life may bring your way! 

Functional Range Conditioning will increase:

  • Functional Mobility (nueral-control & articular strength)
  • Articular Resilience (the tissue’s load bearing capacity)
  • Articular Health and Longevity

Achieving these 3 things can be effective in decreasing injury rates since injuries occur when the load placed on a tissue exceeds the tissue’s ability to absorb it.   For example,  when running,  hamstring strains usually happen during deceleration (during the hamstrings function to slow the swing leg during gait)  – the load exceeds the hamstring’s capability to absorb it. Using principles from the FRC system we can work to increase the capacity of the hamstrings to accept load, therefore, it will “take more to break you” and thus reduce your likelihood for reinjury. 

The Principle of Progressive Adaptation states: Incremental loads imparted on all forms of connective tissues results in adaptation of the connective tissues such that the load absorption capacity improves.

Thus FRC is a means to incrementally increase the load bearing capacity of the tissues composed in joints, granting the body greater freedom during motion, greater ability to accept load, and through this, decreased incidence of injury.

Kinstretch classes are available for groups upon request.

Kinstretch is a movement enhancement system that develops maximum body control and most importantly USABLE ranges of motion. Kinstretch was derived from Functional Range Conditioning.  Kinstretch differs from other movement systems in that it’s focus and priority is mobility over flexibility.  Kinstretch is a type of body weight exercise that will enhance your vitality, reduce chronic pain, and help you become more athletic.

Kinstretch is helpful in counteracting daily life activities that can be harmful to our bodies.  For example many of us sit behind a desk at least five hours a day, then we drive home and sit on the couch and watch television.” This is detrimental to our hips and back.   Taking a Kinstretch class will challenge all your body parts as the positions call for deliberate and slow movements for the shoulders, neck, hips, elbows, toes, ankles,  and other joints. 

The underlying objective of Kinstretch is to improve your movement capacity and variability. This makes our body more resilient and mitigates the chance for injury. While Kinstretch can be an effective movement training system to reduce injury and improve performance, it’s not meant to replace your current training.  Kinstretch should be used to supplement your current training and part of an adjunct training modality.
