HOS-L004 Ladder Barrel is a combination of a wooden ladder and a wooden barrel, connected by a sliding frame with adjustable spacing, suitable for practitioners of different body sizes. Among them, wooden ladders can be used to provide fixed limbs and more support, while the semicircular curvature of wooden barrels can be used to assist in practice or provide challenging elements, helping practitioners cultivate core muscle strength and spinal flexibility in supine, prone, sitting, cross sitting, and kneeling positions.
