Objectives: Determine the effect of an 8-week intervention of the new group fitness program Les Mills Pilates on balance, core stability, abdominal, back, and hip muscle endurance, flexibility, and mood. Research questions: Does doing Les Mills Pilates twice per week for 8 weeks result in: 1) increased balance, 2) increased core stability, 3) increased abdominal, back, and hip muscle endurance, 4) increased flexibility, and 5) improved mood? Intended outcomes: this study will determine the efficacy of a new group fitness program developed by Les Mills International. Results will be used to help refine the program, as well as in marketing of the program.

Twice-weekly mat Pilates class for 8 weeks, either in person or online (depending on participant availability)
Core endurance (time to failure in seconds)
Endurance of the core muscles- abdominals, back extensors, hip extensors, quadriceps- time to hold a plank (abdominals), biering-sorenson test (back extensors), unilateral hip bridge (hip extensors), wall sit (quadriceps) will be recorded. Participants will hold each position until failure. Higher times to reach failure indicate more endurance (better value).
Time frame: 8 weeks
Balance (single leg reach distance in cm)
Y-balance test- distance in cm. Higher distances are better outcomes.
Time frame: 8 weeks
Core stability: Sahrmann trunk stability test
Sahrmann trunk stability test- maximum level participants can perform with neutral lumbar spine. Level 1 (minimum value) to Level 5 (maximum value). Higher scores are better outcome.
Time frame: 8 weeks
Flexibility in cm
Forward reach test. Participants sit with legs extended and reach forward as far as they can. Reach distance is measured. Higher scores are better outcome (more flexibility).
Time frame: 8 weeks
Mood
Perceived motivation, stress and fatigue on 0 (minimum value) -5 (maximum value) Likert scale, where higher numbers indicate more motivation (better outcome), stress (worst outcome), or fatigue (worse outcome)
Time frame: Daily for 8 weeks
