Should my feet be on the ground or elevated during Russian twists?

Keeping your feet on the ground or heels lightly touching provides more stability and is better for learning the movement or using heavier weight. Elevating your feet fully increases the difficulty by requiring more core stabilization throughout the exercise.

How heavy should the dumbbell be for Russian twists?

Start with a light to moderate weight that allows you to complete all reps with controlled rotation and no lower back rounding. Most lifters use significantly less weight than they expect, as maintaining proper form through the full range of motion is more challenging than it appears.

What is the difference between Russian twists and other oblique exercises?

Russian twists emphasize rotational movement through a longer range of motion compared to static holds like side planks. They also train the obliques dynamically in a seated position, which carries over well to rotational sports and movements.

Russian Twist (Dumbbell)

The Russian twist with a dumbbell is a rotational core exercise that targets the obliques while holding a weight at chest level as you twist side to side. It suits lifters looking to build rotational strength and add resistance to their core training.

Muscle group: Core
Primary muscles: obliques
Equipment: Dumbbell

How to do the Russian Twist (Dumbbell)

Sit on the floor with knees bent and feet flat, holding a dumbbell with both hands at chest level.
Lean back slightly to engage your core, keeping your spine straight and chest up.
Lift your feet a few inches off the ground or keep heels lightly touching for more stability.
Rotate your torso to one side, bringing the dumbbell beside your hip while keeping arms relatively still.
Rotate to the opposite side in a controlled motion, moving through your core rather than your arms.
Continue alternating sides for the prescribed number of reps.

Form tips

Keep the movement controlled and deliberate rather than using momentum to swing the weight side to side.
Maintain a neutral spine throughout by keeping your chest up and avoiding rounding your lower back.
Focus on rotating through your torso rather than just moving your arms across your body.

Common mistakes

Rounding the lower back under fatigue reduces core engagement and places unnecessary stress on the spine.
Using momentum to swing the weight quickly diminishes oblique activation and increases injury risk.
Moving only the arms instead of rotating the torso turns the exercise into an arm movement rather than a core exercise.

Sets and reps

For hypertrophy, perform 3 to 4 sets of 12 to 20 reps per side with moderate weight, while strength-focused training typically uses 3 to 4 sets of 8 to 12 reps per side with heavier load.
