Which drill helps maintain a straight spine and promotes body roll in backstroke?

• A. 12 kick switch
• B. Cup drill
• C. Vertical free kicking
• D. Unco drill

Answer: (A)

In backstroke, keeping a long, neutral spine while you rotate your shoulders and hips together is essential for an efficient, powerful stroke. The 12 kick switch drill trains this balance by enforcing a steady kick rhythm while requiring controlled rotation of the body with each cycle. By sticking to a fixed number of kicks before switching, you learn to maintain a elongated spine and a smooth, consistent roll rather than letting the torso bend or twist unevenly. The result is a more stable body line on the water and a cleaner transfer of power from core to kick.

The other drills focus on different aspects: the cup drill targets hand entry and catch mechanics seen in freestyle, not backstroke alignment; vertical free kicking isolates the legs and can neglect the integration of rotation with spine position; the unco drill emphasizes body position and rotation patterns but doesn’t specifically reinforce the cadence that promotes a straight spine together with a coordinated roll.
