Weighted Russian Twist

How to perform the Weighted Russian Twist

1. Sit with knees bent and torso leaned back to about forty-five degrees, holding a dumbbell or plate close to the chest.
2. Adding load to lumbar rotation raises the disc-shear risk, so keep the tempo controlled and never whip the weight around fast.
3. Brace the core hard, then rotate the trunk from the ribcage to move the weight to the outside of one hip.
4. Lead the rotation with the torso and let the arms simply carry the load, keeping it near the body rather than reaching it far out.
5. Turn back through center and rotate smoothly to the other hip, pausing briefly at each end under control.
6. Keep the weight moderate and the spine long — as soon as the movement becomes a fast, jerky swing, the load is too heavy.

Suggested working range: 12–20 reps. Default progression: double progression.

Common mistakes

• •Whipping the weight around fast, which spikes the shear load on the rotating lumbar spine.
• •Reaching the load far out from the body, greatly increasing the leverage on the lower back.
• •Rounding the back in the leaned-back position while adding load, a poor combination for the discs.
• •Going too heavy so the movement turns into a jerky swing instead of controlled rotation.

Variations & alternatives

Swap in a related movement if equipment, recovery, or progression demands it.
