Description

A combination of Russian twist and sit-up performed with an EZ-bar. This exercise targets your abs, obliques, and lower back muscles.

How to Do EZ-Bar Russian Twist Sit-up

1
Setup
Lie supine on the floor with your knees bent at approximately 90 degrees and feet flat on the ground. Hold an EZ-bar with an overhand grip, hands slightly wider than shoulder-width, extending it straight up over your chest.
2
Setup
Engage your core by drawing your navel towards your spine, ensuring your lower back is pressed firmly into the floor to provide a stable base.
3
Exhale as you initiate a sit-up, lifting your torso off the floor while keeping the EZ-bar extended directly above your chest, maintaining a straight arm position.
4
At the top of the sit-up, rotate your torso to one side, twisting your shoulders and the EZ-bar towards that hip, focusing on contracting your obliques.
5
Return to the center briefly, then immediately rotate to the opposite side, twisting the EZ-bar towards the other hip to complete the rotation for one repetition.
6
Inhale as you slowly and with control lower your torso back to the starting supine position, maintaining core engagement throughout the descent.

Tips

Control the entire movement, especially the eccentric (lowering) phase, to maximize muscle engagement and prevent relying on momentum.
Focus on initiating the twist from your obliques and thoracic spine, rather than just swinging your arms or allowing your hips to rotate excessively.
Keep your gaze fixed on the EZ-bar throughout the movement to help maintain a stable head and neck position, moving with your torso.
If your feet lift off the ground, try anchoring them under a stable object or having a partner hold them to ensure proper core activation.

Common Mistakes

×Using excessive momentum to sit up or twist reduces core activation; slow down the movement and focus on controlled abdominal contraction.
×Only performing a partial twist limits oblique engagement; aim for a full, controlled rotation from the torso to each side, leading with the shoulders.
×Arching the lower back excessively can strain the spine; maintain a neutral spine by keeping your core braced and avoiding an exaggerated arch.
