Frequently Asked Questions

How do I perform the sit-and-reach test?

Sit barefoot on the floor with legs extended, feet flat against a box. Without bouncing, reach forward and hold for 2 seconds. Record the furthest point reached.

How can I improve flexibility?

Static stretching held 30–60 seconds, yoga, and daily mobility work improve sit-and-reach scores. Consistency over weeks is more effective than infrequent intense sessions.
