Russian Twist (Kettlebell)

CoreKB

The heaviest and most demanding standard Russian twist variant, using a kettlebell's offset weight distribution to challenge the obliques through a full rotational range with real load.

Sets

3

Reps

16-20 total

Rest

45s

Contraindications

Low back pain when rounded — reduce load and torso angle.

Setup

Sit with knees bent, torso leaned back about 45 degrees, holding a kettlebell by the horns at the chest.

Execution

  1. 1Brace the core hard before rotating
  2. 2Rotate the kettlebell to one side, controlling its weight through the arc
  3. 3Rotate through center to the opposite side
  4. 4Keep the chest tall and avoid rounding under the heavier load
  5. 5Continue alternating for the set

Key cues

  • Control the bell, don't let it control you
  • Rotate the ribcage through the full range
  • Chest stays tall the entire set
  • Breathe out sharply on each rotation

Common faults

  • Using a kettlebell too heavy for controlled rotation
  • Rounding the low back under the heavier load
  • Using momentum to swing rather than controlled rotation
  • Feet flailing if elevated

Tweaks

  • Reduce weight or keep feet down as a regression
  • Add a full range tap to the floor for more range
  • Slow the tempo for more time under tension
