Healthy women aged 18-45 years with BMI \<30 were randomized into two groups to receive either Tai Chi or yoga training. Both interventions were delivered for 8 weeks, 2 sessions per week, 45 minutes per session, at Bahçeşehir University. Flexibility, anxiety, and sleep quality were assessed before and after the intervention using standardized flexibility tests, the Beck Anxiety Inventory, and the Pittsburgh Sleep Quality Index. The outcome assessor was blinded to group assignment.
