Supine Body Twist
From: FM 7-22 October 2012
Purpose: This exercise strengthens the trunk muscles and promotes trunk control (Figure 9-44).
Starting Position: Supine position with hips and knees bent at 90 degrees. Hold one kettlebell over the trunk using a neutral grip with the upper arms off the ground and elbows bent 90 degrees. To assume the starting position from the position of attention with the kettlebell on the ground, (1) assume the seated position and grasp a single kettlebell at each side of the handle with palms facing inward, (2) assume the supine position, (3) raise the kettlebell to the starting position over the trunk and raise the feet off the ground.
Cadence: SLOW
  1. Rotate the kettlebell to the left and the legs to the right.
  2. Return to the starting position.
  3. Rotate the kettlebell to the right and the legs to the left.
  4. Return to the starting position.
