EZ-Bar Legs Side Pull-In Sit-Up

Body Part: Waist

Muscle: Abs

Equipment: EZ Barbell

EZ-Bar Legs Side Pull-In Sit-Up is a floor core exercise that combines a diagonal sit-up with a leg pull-in to challenge the rectus abdominis, obliques, and hip flexors together. The bar is there as a fixed hand position and counterbalance, so the torso has to stay organized while the legs and ribs work through a more demanding pattern than a basic crunch. It is useful when you want abdominal work that also asks for coordination, not just repetition speed.

The setup matters because the movement only stays clean if the low back, shoulders, and pelvis are arranged before you start. Lie on your back on a mat, grip the ez bar evenly with both hands, and keep your arms steady above the chest or slightly overhead depending on the starting position you can hold without shrugging. From there, lengthen the legs, then angle them toward one side so the first rep begins with the hips controlled and the ribs already tucked down. A tight setup keeps the pull-in coming from the trunk instead of from swinging legs.

Each rep should feel like a diagonal curl, not a jerky leg throw. Pull the knees or lower legs toward one hip as you lift the shoulders off the floor, then keep the chest moving toward the pelvis until the abs are fully shortened. Pause briefly at the top, then lower the upper back, pelvis, and legs together under control so the bar and lower body stay coordinated. Exhale as you rise, inhale on the way down, and keep the neck long so the jaw and shoulders do not take over.

Use EZ-Bar Legs Side Pull-In Sit-Up as accessory core work, as part of an abdominal circuit, or when you want a challenging floor variation that teaches control through rotation and flexion at the same time. It works best with a small to moderate range of motion done smoothly; the set should end when the bar starts wobbling or the legs can no longer stay on the chosen side. If your lower back arches, shorten the lever by bending the knees slightly and reducing the leg travel. If the exercise is performed cleanly, it builds solid trunk stiffness without needing heavy load.

Instructions

• Lie face up on a mat and grip the ez bar evenly with both hands, with your hands just wider than shoulder width.
• Extend your arms so the bar stays steady above your chest or slightly overhead, and lengthen both legs on the floor.
• Brace your abs, press your low back toward the mat, and turn the toes slightly out so your hips stay quiet.
• Lift both legs a few inches and angle them toward one side, keeping the knees softly bent if your hamstrings are tight.
• Begin the sit-up by curling your ribs toward your pelvis while keeping the bar fixed in your hands.
• Pull the legs diagonally in toward the same side as the curl until your shoulders are off the floor and your abs are fully shortened.
• Pause briefly at the top, then lower your shoulders and legs together under control without letting the bar drift.
• Reset your breath at the bottom, switch the leg angle to the other side on the next rep, and repeat for the planned set.

Tips & Tricks

• Keep your elbows almost locked so the bar does not turn into a press.
• Let the legs travel diagonally, not straight up; that keeps the obliques involved.
• If the low back lifts early, bend the knees more and shorten the leg pull-in.
• Lower for a full count or two; the eccentric matters more than the top squeeze here.
• Keep the chin slightly tucked so the neck does not lead the crunch.
• A lighter bar is better; the goal is coordination, not heavy loading.
• Alternate sides evenly so one hip does not dominate the pattern.
• Stop the set when your shoulders start yanking or the bar starts drifting.

Frequently Asked Questions

What muscles does EZ-Bar Legs Side Pull-In Sit-Up work?

It primarily trains the abs, with the obliques and hip flexors helping during the diagonal pull-in and curl.

Is the ez bar meant to be lifted like a weight?

No, it works more like a fixed hand position and counterbalance. Keep it steady rather than trying to press or swing it.

Should my legs stay straight or bent?

Straight legs make the movement harder, but a slight knee bend is fine if your low back arches or your hamstrings are tight.

Do I alternate sides every rep?

Usually yes, alternating sides keeps the work balanced. If you feel one side lagging, you can also do a set to one side and then repeat on the other.

How high should I come up on the sit-up?

Lift until your shoulders clear the floor and your ribs close toward your pelvis. You do not need to sit all the way up.

Can beginners do EZ-Bar Legs Side Pull-In Sit-Up?

Yes, but start with a shorter leg travel and a lighter setup, or even no bar, until you can keep the low back controlled.

Why do I feel this in my hip flexors so much?

The leg pull-in makes the hip flexors work hard. Reduce the range and slow the lowering phase if they take over from the abs.

What is the best substitution if I do not have an ez bar?

Use a light dowel, a fixed overhead hand position, or a regular leg pull-in sit-up and keep the arm position steady for the whole set.
