core training

A woman in a black long-sleeve top and colorful leggings performs a handstand against a grey wall in a narrow corridor, her legs extended vertically and then kicked back down in a continuous loop. She maintains the handstand position, pushing off the wall with her feet to reverse the motion, moving between a vertical handstand and a low, arched pose with her hands on the floor and her body nearly horizontal. The setting is a concrete corridor with a "WC" sign on the floor and a "C108" sign on the wall.
