The vertical leg raise on parallel bars is a bodyweight core exercise that targets the iliopsoas and rectus abdominis by raising the legs while the body is suspended vertically between the bars. The obliques, quadriceps, and tensor fasciae latae assist throughout the movement. It is well suited for building hip flexor strength and lower abdominal development without spinal compression.
How to do the Vertical Leg Raise (on parallel bars) (VERSION 2)
- 1Stand between a set of parallel bars and grip each bar firmly with an overhand grip, palms facing inward.
- 2Press through your palms to lift your body off the ground so your arms are fully extended and your torso hangs vertically.
- 3Let your legs hang straight down with your feet together and your body in a neutral, upright position.
- 4Brace your core and tilt your pelvis slightly posterior to engage the rectus abdominis before initiating the lift.
- 5Keeping your legs as straight as possible, raise them in front of you by flexing at the hips until your thighs are parallel to the floor or higher.
- 6Pause briefly at the top of the movement, maintaining tension in the abs and hip flexors.
- 7Lower your legs slowly and under control back to the starting position without swinging or using momentum.
- 8Repeat for the desired number of repetitions, keeping your upper body stable throughout each rep.
Form tips
- Keep a slight posterior pelvic tilt throughout the set to ensure the rectus abdominis remains engaged rather than relying solely on the hip flexors.
- Press firmly into the bars with your palms and keep your shoulders packed down to avoid shrugging and losing upper-body stability.
- Exhale as you raise your legs and inhale as you lower them to maintain intra-abdominal pressure and protect the lower back.
- If straight-leg raises are too demanding, begin with a bent-knee variation and gradually work toward full leg extension as hip flexor strength improves.
- Control the descent — do not let gravity drop your legs. A slow, deliberate lower is where much of the strength adaptation occurs.
Common mistakes
- Swinging the legs: using momentum to swing the legs up reduces the demand on the iliopsoas and rectus abdominis and increases injury risk to the lower back and shoulder joint.
- Shrugging the shoulders: allowing the shoulders to rise toward the ears shifts load onto the traps and compromises bar grip stability, making the movement less safe and less effective.
- Letting the hips drop into anterior tilt: an excessive arch in the lower back at the start or during the lift moves stress away from the abs and into the lumbar spine.
- Cutting the range of motion short: stopping well below parallel limits activation of the upper rectus abdominis; aim to bring the thighs to at least parallel for full muscle recruitment.
- Holding the breath: breath-holding through the entire set can spike blood pressure; use a controlled exhale on the way up to maintain safe intra-abdominal pressure.
Frequently asked questions
What is the difference between a vertical leg raise on parallel bars and a hanging leg raise?
In the parallel bars version, your forearms or palms rest on the bars and your torso is supported vertically, which makes it easier to isolate the core without fighting shoulder and grip fatigue. A hanging leg raise uses a pull-up bar where you hang freely, adding grip and shoulder endurance demands on top of the core work.
Should I keep my legs straight or bend my knees during vertical leg raises?
Straight-leg raises produce greater hip flexor moment and more rectus abdominis involvement, making them the harder option. Bent-knee raises reduce the lever arm and are a good starting point if your hip flexors are not yet strong enough to control straight legs. Progress to straight legs once you can complete bent-knee raises with full control.
How high should I raise my legs?
Aim to bring your thighs at least parallel to the floor. Raising further — toward a 90-degree hip angle or beyond — increases rectus abdominis activation, but only go as high as you can while keeping the movement controlled and your lower back flat.
How many reps and sets should I do?
For strength and muscle development, 3–4 sets of 8–15 controlled reps is a practical range. Prioritize full range of motion and a slow lower over hitting a specific rep count, especially early in training.
Can vertical leg raises cause lower back pain?
They can if performed with an excessive lumbar arch or with momentum. Keeping a slight posterior pelvic tilt, bracing the core before each rep, and lowering the legs slowly rather than dropping them will substantially reduce lower back stress.
