Russian Twist: How-to, Benefits & Variations
The russian twist targets obliques, rectus abdominis, and core. Sit leaned back, knees bent, rotate torso side to side. Builds rotational core strength and supports lower back health.
Russian Twist: How-to, Benefits & Variations
Reaching behind you to grab a seatbelt. Twisting to check a blind spot. Picking up a bag from the floor on your left side. All rotation. All obliques. And rotation is the movement pattern that disappears first when people stop training.
Your obliques don't just flex your trunk forward. They rotate it. A 2022 systematic review of core activation patterns found that rotational exercises produced significantly higher oblique engagement than static holds or flexion-only movements. The russian twist is the simplest loaded version of that pattern.

How to Do Russian Twist
Sit on the floor with your knees bent, feet flat. Lean your torso back about 45 degrees until you feel your core switch on. Sophie Jones cues this perfectly: lean back, tuck the pelvis underneath, belly button towards the spine.
Keep your chest open and shoulder blades pinched back. Hold a dumbbell horizontally at chest height with both hands. If you don't have a weight, clasp your hands together.
Squeeze your legs tight together. This is non-negotiable. Sophie is relentless on this: as soon as your legs start swinging, you're stealing work from your core and handing it to momentum.
Rotate your torso to the right, driving the weight toward your right hip. Beth Hannam cues: aim to tap the floor each time. The rotation comes from your ribcage, not your arms waving side to side.
Rotate back through center and over to the left hip. Exhale as you twist to deepen the contraction. Your gaze stays forward to protect your neck.
Keep your heels lightly touching the floor for stability. Only lift your feet if you can do it without your knees wobbling. Sophie's rule: I would much rather you be here with feet down than legs off the floor and swinging.
Muscles Worked
Primary
Obliques (internal & external)
Power the rotation through your torso. The external obliques on the side you're twisting toward contract concentrically, while the opposite side's internal obliques fire to control the movement. Sophie cues: really get that nice rotation so we can get into those obliques.
Rectus abdominis
Stabilizes your trunk in the leaned-back position throughout the entire set. It's working isometrically the whole time, which is why your abs burn even though you're not doing a crunch.
Transverse abdominis
The deep core muscle that acts as an internal corset. It fires to maintain intra-abdominal pressure when you brace. Without it, your lower back takes the hit.
Secondary
Hip flexors (iliopsoas)
Hold your legs in the elevated position when feet are off the floor. This is why your hip flexors fatigue during feet-up variations.
Erector spinae
Maintain spinal extension in the leaned-back position. They work overtime to prevent your lower back from rounding.
Quadratus lumborum
Assists with lateral flexion and anti-lateral flexion during the twist. This deep back muscle is often weak in people with chronic low back pain.
Why this matters in perimenopause
The russian twist muscles worked are exactly the ones that deteriorate fastest without training. A 2023 systematic review of 27 RCTs found resistance training improved lean body mass, handgrip strength, and knee extension strength in menopausal women. The core muscles don't get the same attention as legs and glutes, but they're the foundation everything else sits on. Weak obliques mean poor posture, poor balance, and a higher fall risk. A 2022 meta-analysis confirmed motor control exercises targeting the core significantly reduced chronic low back pain. Your spine doesn't care about aesthetics. It cares about stability.
Coach's Tips
"As soon as your legs start swinging like this, we're just taking that momentum out of the core." That's Sophie Jones mid-set, catching the exact mistake I see in 9 out of 10 people. Your legs should be bolted together. The instant they start swaying, the russian twist form breaks down and your hip flexors take over.
Sophie Jones
"Cross those feet over, hands come together, and we twist, aiming to tap the floor each time." Beth Hannam's setup cue. Crossing your ankles locks your lower body in place so the rotation has to come from your trunk. The tap-the-floor target gives you a consistent range of motion to hit every rep.
Beth Hannam
"Making sure our pelvis is underneath, so we wanna get belly button towards the spine." Sophie's pelvic tuck cue fixes the most dangerous russian twist mistake. If your pelvis tilts forward (anterior tilt), your lower back hyperextends under rotational load. Tucking under braces the spine.
Sophie Jones
"I'm still keeping my focus forward... taking that weight side to side." Danielle Harrison's gaze cue. Where your eyes go, your neck follows. If you turn your head to watch the weight, you load your cervical spine asymmetrically. Eyes forward, weight moves to the hips.
Danielle Harrison
"Try to keep the pelvis still... you don't want them kind of shearing side to side." Lianna Brice isolates the critical difference between a good and bad russian twist. Your hips are the anchor. Your ribcage is the thing that moves. If the pelvis is rocking, you're not rotating. You're just wobbling.
Lianna Brice
Exhale as you twist to each side. This isn't optional. Exhaling on the rotation deepens the oblique contraction and recruits the transverse abdominis. I cue this constantly because most people hold their breath through the entire set, then wonder why their face is beet red and their core feels weak.
Sophie Jones
"Heels lightly touching the floor... Leaning back, making sure pelvis is tucked underneath." Sophie gives permission to keep feet down. Too many people rush into the feet-elevated version because it looks harder. Harder doesn't mean better. A controlled russian twist with feet planted builds more oblique strength than a sloppy one with legs flailing in the air.

Why This Matters for You
I'm going to be blunt about why rotational core training matters during perimenopause. It's not about flat abs. It's about staying sharp on your feet.
Stepping off a curb wrong. Slipping on a wet floor. Getting bumped sideways while carrying groceries. The muscles that catch you in those moments are the obliques and the deep rotational stabilizers — the same muscles the russian twist trains. A 2023 systematic review of strength exercises for menopause found resistance training reduced symptom severity across the board, including fatigue, mood disturbance, and musculoskeletal pain.
But here's the part nobody talks about. Estrogen directly affects fascial elasticity and tendon stiffness. When estrogen drops, your connective tissue changes. Rotational movements like the russian twist keep your thoracolumbar fascia loaded and responsive. Skip rotation training and the mid-back stiffens, the lower back compensates, and you wake up one morning barely able to turn to look at your alarm clock.
Three sets. Twice a week. That's the dose. You don't need to love it. You need to do it.
Variations & Modifications
Feet-Down Russian Twist
lowKeep your heels on the floor the entire time. No weight. This is where I start everyone, zero exceptions. You build rotational control before adding load or instability. Sophie literally says: I would much rather you be here than legs off the floor and you're swinging. She's right.
Weighted Russian Twist
mediumHold a dumbbell horizontally and drive it toward each hip. Sophie cues: trying to drive that dumbbell down, get as many obliques contracted as I can. The weight adds resistance to the rotation, but only add it once you can do 15 controlled bodyweight reps with feet down.
Feet-Elevated Russian Twist
medium-highLift your feet off the floor and balance on your sit bones. This recruits your hip flexors and demands much more from your transverse abdominis. Sophie's test: can you do it without your knees swinging side to side? If not, feet go back down. Ego has no place here.
Legs-Crossed Russian Twist
mediumCross your ankles and keep legs elevated. Beth Hannam's preferred setup: cross those legs, reach to the left, reach to the right, aiming to get that rotation through the midline. Crossing the ankles locks your lower body and prevents the knee-swing problem.
Decline Russian Twist
highHook your feet under a decline bench and lean back further than the floor version allows. This increases the lever arm on your rectus abdominis and obliques. Not for beginners. You need a solid 20 controlled reps of weighted floor russian twists before attempting this.
Benefits
Trains rotation, the forgotten movement pattern
Most core work is sagittal plane only: crunches, planks, leg raises. The russian twist benefits your body by training the transverse plane. A 2022 systematic review found rotational and anti-rotation exercises produced significantly higher oblique activation than flexion-based movements. Life happens in rotation. Train for it.
Builds oblique strength without equipment
You need nothing. A patch of floor. Your bodyweight. Done. The russian twist is one of the few oblique exercises that doesn't require a cable machine, stability ball, or gym membership. Add a dumbbell when you're ready, but the bodyweight version alone builds real rotational strength.
Protects the lower back
This sounds counterintuitive since poorly done russian twists can aggravate the back. But a controlled russian twist with a tucked pelvis strengthens the exact muscles that stabilize your lumbar spine. A 2022 meta-analysis found motor control exercises targeting the core significantly reduced pain and disability in chronic low back pain patients.
Keeps you steady when life gets sideways
Strong obliques are the unsung heroes of balance. They prevent lateral sway and control deceleration when you stumble on a trail, slip on ice, or catch yourself carrying something heavy. During perimenopause, estrogen decline affects proprioception and reaction time. Training rotation builds the reflexive core stability your body needs before it needs it.
Low time investment, high core payoff
Three sets of 20 total reps (10 each side) takes about 90 seconds. You can slot it into any workout as a finisher. The russian twist exercise fits anywhere because it doesn't fatigue your legs, shoulders, or grip.
Common Mistakes to Avoid
Legs swinging side to side
Sophie hammers this one: your legs should be bolted together, not swaying with each twist. If they swing, you're using momentum, not your obliques. Cross your ankles (Beth's cue) or plant your heels on the floor. If it still happens, the weight is too heavy.
Moving just the arms instead of the torso
Natalia Gunnlaugs catches this: make sure that you're twisting the core, not just moving the arms. If your belly button is pointing forward the whole time and only your hands move, your obliques aren't working. Your ribcage needs to rotate. Your navel should face the direction you're twisting toward.
Pelvis not tucked (anterior tilt)
If your lower back arches during the russian twist, you're loading your lumbar spine under rotation. That's a recipe for disc irritation. Sophie's fix: tuck the pelvis underneath, belly button towards the spine. Think about flattening your lower back, not arching it.
Turning the head to follow the weight
Your eyes should stay forward. Danielle Harrison cues: I'm still keeping my focus forward. Turning your head loads the cervical spine asymmetrically and can cause neck strain. Let the weight go to your hips while your gaze stays fixed on the wall in front of you.
