Yoga — Evidence-Based Benefits

• Flexibility. Held and dynamic postures increase range of motion at the hips, spine, shoulders, and hamstrings; flexibility is the most consistently reported physical adaptation (Benefits and Outcomes of Flexibility Exercise).
• Balance. Single-leg and transitional postures plus gaze fixation improve static and dynamic balance; meta-analyses report significant balance improvement in older adults, supporting fall-prevention programming (Fall Prevention for Older Adults (Overview)).
• Strength. Load-bearing postures (planks, chaturanga, warriors, arm balances) build muscular endurance and strength, especially in power/Vinyasa styles.
• Stress and mood. Reviews report reduced stress, anxiety, and depressive symptoms across healthy and clinical groups; slow yogic breathing raises vagal tone and is associated with lower cortisol (Stress-Management Techniques).
• Low back pain. Used as an evidence-supported adjunct for chronic non-specific low back pain, reducing pain and disability (Low-Back Pain).

Benefits are dose-dependent and style-dependent; cardiometabolic gains are modest except in vigorous styles. Keep claims grounded in measured outcomes, not energetic or mystical mechanisms.

• Strongest evidence: flexibility, balance, mood/stress.
• Older-adult meta-analyses: significant balance, flexibility, strength, and depressive-symptom improvements.
• Adjunct for chronic low back pain.
• Cardiometabolic benefit mainly from power/Vinyasa.
