The EZ-bar Russian twist sit-up is a weighted core exercise that combines a full sit-up with a rotational twist while holding an EZ barbell. It trains the rectus abdominis through the sit-up, the obliques through the twist, and the iliopsoas as the hip flexors lift your torso, making it a strong choice for building both flexion and rotational core strength.
How to do the EZ-Bar Russian Twist Sit-up
- 1Sit on the floor with your knees bent and feet flat, anchoring them under a heavy object or having a partner hold them down.
- 2Grip an EZ barbell with both hands on the angled inner grips and hold it across the front of your chest or shoulders.
- 3Brace your core and lower your torso back toward the floor under control until your shoulder blades are near the ground.
- 4Curl back up into a full sit-up, leading with your chest and keeping the EZ bar close to your body.
- 5Near the top of the sit-up, rotate your torso to one side until the bar points over that hip.
- 6Twist back through the center and rotate to the opposite side, keeping the movement controlled rather than swinging.
- 7Return to center, then lower your torso back down to begin the next repetition.
- 8Complete your reps, then set the EZ bar down safely under control.
Form tips
- Move slowly through the twist so the obliques do the work, rather than using momentum to throw the bar side to side.
- Keep the EZ bar close to your chest to reduce strain on your lower back and shoulders during each rotation.
- Exhale as you sit up and rotate, and inhale as you lower back toward the floor.
- Start with a light EZ bar or no added weight until your sit-up and twist mechanics are clean, then add load gradually.
- Keep your neck relaxed and your chin slightly tucked so you don't yank your head forward as you rise.
Common mistakes
- Pulling with your arms or swinging the bar to generate momentum, which takes tension off the abs and obliques and turns the lift into a swing.
- Letting your lower back arch and your torso flop down at the bottom, which strains the spine instead of staying under control.
- Rotating only your arms and shoulders while your torso stays square, which removes the work from the obliques.
- Holding the bar far out in front of you, which overloads the lower back and shoulders and makes the rep harder to control.
- Using a weight too heavy to control, causing you to jerk through reps and lose the deliberate twist at the top.
Frequently asked questions
What muscles does the EZ-bar Russian twist sit-up work?
It targets the rectus abdominis through the sit-up motion, the obliques through the rotational twist, and the iliopsoas (hip flexors) as they lift your torso off the floor.
Is the EZ-bar Russian twist sit-up good for beginners?
It's better suited to those with some core experience, since it combines a weighted sit-up with rotation. Beginners should master the bodyweight sit-up and Russian twist separately before holding an EZ bar.
How many sets and reps should I do?
Three to four sets of 10 to 15 controlled reps per side is a sensible range for most lifters. Prioritize clean rotation over chasing heavier weight or higher reps.
Do I need to anchor my feet?
Anchoring your feet under a heavy object or having a partner hold them down helps you sit up fully with the added weight. Without an anchor you may struggle to complete the sit-up portion under load.
