Primary purpose: TREATMENT

Brief summary: Does a rotary based triplanar exercise intervention that utilizes the trunk as a proximal lever, strengthen the hip and alter dynamic LE alignment in running females?

Detailed description: Current hip-focused programs fail to alter hip adduction angles in females while performing higher speed and more complex maneuvers such as running.

(Willy, et al., 2011) - 10 female runners, underwent 6 wk. hip focused intervention, change in SLS but NO change in hip adduction angle while running.

A different intervention strategy that includes utilizing the trunk as the proximal lever to strengthen the hip, could potentially alter biomechanical outcomes such as hip adduction angles in female runners.

This study will apply a new intervention model and then measure running, single leg squat and hip strength to determine if a newly informed intervention can alter LE kinematics in females while running and make improvements in hip strength following the intervention Inclusion Criteria

* 18 years old or greater
* Female Exclusion Criteria
* Injury of the lumbar spine, hips, knees or foot/ankle in the last 6mos that required medical attention
* any surgery of the lower back or the pelvis or lower extremities any time in the subjects life

Eligibility criteria: Inclusion Criteria:

* 18\> year old female; must be able to run on the treadmill for 5-7 min and perform a single leg squat

Exclusion Criteria:

* surgery to the LB or lower extremities Significant injury (seeking medical attention) to the LB or LEs in the last 6mos.
