How to do it

Starting position

  1. Sit on the floor and bend your knees slightly.
  2. Bring your hands together and hold them in front of your chest.
  3. Rest your heels lightly on the floor and find your balance.
  4. Straighten your back and brace your abs.

Movement

  1. Maintain your upper body position and rotate your torso to the right.
  2. Rotate to the opposite side while feeling the tension in your abs.
  3. Alternate sides and repeat the movement.

Breathing

Exhale as you rotate your torso and inhale as you return to center.

Trainer tips

  • Lean your upper body back 45 degrees and hold it in place
  • Twist your entire torso up to your shoulders
  • Holding a plate increases the difficulty

Cautions

  • If your back rounds, it strains your lumbar spine, so keep your spine straight.
  • Swinging only the arms side to side
  • Rounding the back

If you feel pain during the exercise, stop. If it continues, talk to a professional.
