Russian Twist.

Make every rep count.

1. 01

   Lie on a mat and bring your knees up so your hips and knees are bent to about 90° (shins parallel to the floor).

2. 02

   Stack your hands together with arms straight up over your chest, palms facing your feet.

3. 03

   Brace your core and gently tuck your ribs down.

4. 04

   Lift your head and shoulder blades a few inches off the mat (keep your lower back in contact with the floor).

5. 05

   Keeping your arms stacked, rotate through your torso and reach your hands to the left, then rotate to the right—move with control, not momentum.

6. 06

   Return to center and lower your shoulder blades back to the mat.

7. 07

   Repeat for the prescribed reps.

8. 08

   Coaching cues / options

9. 09

   The higher you lift your shoulder blades, the more challenging it gets—only lift as high as you can while staying controlled.

10. 10

    To progress, hold a dumbbell/weight with both hands (keep shoulders down and avoid yanking your neck).
