Slant Board Jefferson Curl / Forward Fold
Stand on a slant board with knees locked out and quads flexed. Slowly round down segment by segment to touch the floor or lower an unloaded/light barbell below the feet. Key points: - Keep quads actively flexed and knees fully extended throughout - Roll down vertebrae by vertebrae through full spinal flexion - Grip the board with foot muscles for stability Common mistakes: Bending the knees to reach the floor or moving too quickly into end range.
