How to Do the Vertical Leg Raise (on Parallel Bars)

Follow these steps to perform the Vertical Leg Raise (on Parallel Bars) with correct form:

1Hang from the parallel bars with your arms fully extended and your body straight.
2Engage your core and lift your legs up in front of you, keeping them straight.
3Continue lifting until your legs are parallel to the ground or slightly higher.
4Pause for a moment at the top, then slowly lower your legs back down to the starting position.
5Repeat for the desired number of repetitions.

Muscles & Anatomy

The captain's chair leg raise (vertical leg raise on parallel bars) trains the rectus abdominis and hip flexors (iliopsoas and rectus femoris) through hip flexion — lifting the legs from a hanging position. Unlike floor crunches that flex the spine, the leg raise flexes the hip, which activates the hip flexors more directly. The rectus abdominis works isometrically to prevent lumbar hyperextension as the legs lift and eccentrically to lower the pelvis. The hanging arm support position means the shoulders and upper back work isometrically to maintain the body in suspension, adding secondary stimulus to the lats and triceps.

Pro Tips for Better Results

1Tilt your pelvis posteriorly (round your lower back) at the top of each rep. If you only raise the legs without posterior pelvic tilt, the rectus abdominis is a secondary player to the hip flexors. The posterior pelvic tilt is the key to making this an ab exercise.
2At the top of the movement, pause for 1–2 seconds. This pause forces the abs to hold the spinal flexion isometrically and is where most of the rectus abdominis work happens.
3Lower the legs with a 3-second eccentric count. The descent is where you're fighting gravity — doing it slowly greatly increases time under tension in both the abs and hip flexors.

Common Mistakes to Avoid

✗ Swinging the legs with momentum

Fix: Pause at the bottom of each rep in the fully extended position before initiating the next rep. Swinging uses momentum entirely — the muscles do almost no eccentric work.

✗ Not tilting the pelvis at the top

Fix: At the top of the movement, think of 'pushing your belly button to your spine' and rounding the lower back slightly. Without this posterior pelvic tilt, the abs barely participate — it's a hip flexor exercise only.

✗ Letting the body swing backward as legs rise

Fix: Actively press the forearms and elbows into the pads throughout. This stabilizes the torso and prevents the lever-like backward swing that dissipates core tension.

✗ Using bent-knee raises as a permanent substitute instead of a progression

Fix: Bent-knee raises are easier because the moment arm is shorter. Progress toward straight-leg raises over time — they dramatically increase the load on the hip flexors and abs.

How to Program the Vertical Leg Raise (on Parallel Bars)

Sets & Reps

3–4 sets of 10–20 reps. Add ankle weights when bodyweight becomes easy. Progress toward toes-to-bar (touching the bar with straight legs) as the advanced standard.

Frequency

3 times per week. Core training frequency can be high because the exercise doesn't generate significant muscle damage at submaximal efforts.

Where to Place It in Your Workout

Use as a primary core exercise early in a core circuit, or as a finisher after lower-body training. The hip flexor fatigue from this exercise won't affect leg press or squat performance if done after compound lower-body work.

How to Progress

Bent-knee raise → straight-leg raise → ankle weights → medicine ball between feet → toes-to-bar. Each progression significantly increases the mechanical difficulty.

Variations & Alternatives

Hanging Leg Raise (Bar)

Hang from a pull-up bar and perform the same motion. Adds a grip and shoulder endurance challenge. The body swings more freely, which makes stabilization harder and is a more advanced variation.

Decline Bench Leg Raise

Lie on a decline bench and raise the legs. Provides a more supported position than hanging and is easier to control the range of motion. A good regression for those not yet strong enough for hanging versions.

Dragon Flag

The most advanced progression: anchor the shoulder and extend the entire body away from the bench in a straight line, then lower under control. One of the most difficult core exercises and a benchmark of elite core strength.
