The purpose of this study is to determine if activation training of the hip musculature affects muscle activation and frontal plane mechanics in healthy individuals.
Specific Aim 1: Determine whether performance on the forward step-down test (FSDT) changes after an eight-week home exercise program (HEP) focused on hip musculature activation in healthy individuals.
Specific Aim 2: Determine whether surface electromyography (sEMG) hip musculature changes following an eight-week HEP focused on hip musculature activation in healthy individuals.
Specific Aim 3: Determine whether a dose-response relationship exists between compliance on the HEP and changes in FSDT scores in healthy individuals.
Specific Aim 4: Determine whether a dose-response relationship exists between compliance on the HEP and sEMG changes in hip musculature activation in healthy individuals.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Arm 1 | Experimental | Participants will undergo lower extremity movement assessment on the Forward Step Down Test before and after a home exercise program (HEP) consisting of five hip activation exercises. These exercises will be performed 2x/week for 8 weeks. Surface EMG of the gluteus maximus and medius, in addition to tracking of participant compliance on the HEP program will also be assessed pre- and post-intervention. |

sEMG data for the gluteus medius, including both mean EMG activation and peak EMG activation will be recorded during performance of the Forward Step Down Test. |
| Pre- and Post- Intervention Program (8 weeks) |
| Home Exercise Program (HEP) Compliance | Participants will complete a log of the number of HEP sessions they complete during the 8-week intervention program. The sum of sessions completed will be used as a measure of compliance. | Pre- and Post- Intervention Program (8 weeks) |
