Which of the following is a Step Barrel exercise for spinal extension?

• A. Low Bridge
• B. Side Stretch
• C. Oblique Roll Down
• D. Swan Dive

Answer: (A)

The move being tested is about spinal extension on the Step Barrel, and which exercise on that apparatus specifically trains that backbend.

Low Bridge on the Step Barrel is designed to create spinal extension by lifting the hips and allowing the spine to lengthen over the curved surface with the feet grounded. This setup encourages controlled, articulate extension through the thoracic and lumbar regions while maintaining a stable pelvis and shoulders, making it the best fit for practicing extension on this apparatus.

Side Stretch targets lateral flexion and reaching the side of the body, not the upward lengthening of the spine. Oblique Roll Down focuses on spinal flexion with oblique engagement, not extension. Swan Dive is a back-extension movement, but it’s not a standard Step Barrel exercise in the repertoire, and it’s typically performed on other equipment or mats.
