The purpose of this research is to determine the impact of a hip activation home exercise program (HEP) compared to a hip activation + single leg balance HEP on performance of the Forward-Step-Down Test (FSDT) in healthy females. Participants will be assigned to the control (hip activation HEP only) or experimental (hip activation + single leg balance HEP). Following the pre-test data collection, participants will complete their HEP for 8 weeks. They will return to the lab for post-test measurements.

Sidelying hip abduction, side plank with hip abduction, clamshell (hip abduction + external rotation), side plan with clamshell, and quadruped fire hydrant exercises will be performed for 1 minute isometric holds, 2 times per week for 8 weeks.
Hip activation HEP: Sidelying hip abduction, side plank with hip abduction, clamshell (hip abduction + external rotation), side plan with clamshell, and quadruped fire hydrant exercises will be performed for 1 minute isometric holds, 2 times per week for 8 weeks. Single leg balance: variety of single leg balance exercises with different upper extremity and lower extremity positions to provide different balance stimuli. Weeks are alternated performing these exercises with eyes open and eyes closed.

Forward-Step-Down Test
a step-down task that is performed off a 20 cm box. Five repetitions are performed to give one score (minimum score 0, maximum score 6). A higher score is worse.
Time frame: pre-intervention (baseline), post-intervention (8 weeks)
surface electromyography (sEMG) peak
The peak sEMG will be collected from the dominant side's gluteus maximum and gluteus medius muscles. The sEMG will be collected during both the FSDT and unipedal stance test
Time frame: pre-intervention (baseline), post-intervention (8 weeks)
surface electromyography (sEMG) mean
The mean sEMG will be collected from the dominant side's gluteus maximum and gluteus medius muscles. The sEMG will be collected during both the FSDT and unipedal stance test
Time frame: pre-intervention (baseline), post-intervention (8 weeks)
Unipedal Stance Test (UPST)
The time a participant can stand on one leg will be collected for eyes open and eyes closed conditions.
Time frame: pre-intervention (baseline), post-intervention (8 weeks)
Dose-Response
The dose-response for outcome 1, 2, and 3 will be calculated, using participant's self-reported exercise compliance as the dose.
Time frame: post-intervention (8 weeks)
