V-Sit

The V-sit is a bodyweight isometric core hold performed on the floor that trains the rectus abdominis and hip flexors by balancing on the sit bones with legs and torso raised. Where a hollow hold keeps the whole spine on the floor and a V-up moves through the position, the V-sit parks you at the hardest point of that arc, so the hip flexors work near their shortest length while the abs keep the lower back from collapsing. Gymnasts and calisthenics athletes program it as a static core drill at the end of a skill session.

What Muscles Does the V-Sit Work?

• Primary: Rectus abdominis, iliopsoas and rectus femoris (hip flexors)
• Secondary: Tensor fasciae latae, adductor longus, quadriceps holding the knees straight
• Tertiary: Transversus abdominis, obliques, serratus anterior

How Do You Set Up for the V-Sit?

Sit on a mat with your legs straight and together in front of you and your hands flat on the floor beside your hips, fingers pointing forward. Sit tall on your sit bones, pull your ribs down toward your pelvis and lengthen the back of your neck. Point your toes, squeeze your thighs together and take a breath in, holding tension through your abs while your feet are still resting on the mat.

How Do You Perform the V-Sit?

1. Lean your torso back a few degrees so your weight shifts onto the back of your sit bones with your hands still on the floor.
2. Raise both legs together, knees locked and toes pointed, until your feet sit at eye level or higher.
3. Lift your hands off the floor and reach them forward alongside your knees so your body forms a V balanced on the sit bones.
4. Hold the position for the target time, breathing shallowly and keeping the ribs down and the chest open.
5. Lower your hands to the floor beside your hips, then lower your legs slowly until your heels touch the mat.
6. Return to the tall seated position with hands down and legs flat before the next hold.

What Are the Key Form Cues?

• Reach your toes away: Push the feet toward the far wall so the legs stay long and the balance point stays behind the hips.
• Ribs down, chest open: Keep the lower ribs pulled toward the pelvis while the collarbones stay wide, so the spine stays long rather than rounded.
• Squeeze the inner thighs together so the legs move as one lever.
• Find the balance point by moving the torso, never by bending the knees.
• Breathe through your nose in short sips so bracing never slackens mid-hold.

What Are the Most Common Mistakes?

• Sitting too far back: The lower back rounds, the hip flexors go slack and the hold becomes a slump on the tailbone. Lean forward until the abs, not the spine, carry the load.
• Bending the knees: A tucked V shortens the lever and drops the difficulty by half. Keep the knees locked or scale the hold instead.
• Flexing the hip flexors alone with a hyperextended lower back: The lumbar spine arches under the pull of the psoas and the vertebral joints take the strain. Keep the ribs down so the abs share the work.
• Holding the breath: A single locked breath ends the set early. Keep small breaths moving.
• Shrugging the shoulders toward the ears: Tension in the neck steals attention from the trunk. Reach the arms long and keep the shoulders down.

What Are the Best V-Sit Variations?

• Tuck sit: Knees bent and pulled to the chest, the entry-level version for building balance.
• Straddle V-sit: Legs held wide apart raise the feet higher and demand more hip flexor strength.
• Elevated V-sit on parallettes: Hands on push-up bars let the legs pass higher for a steeper V.
• Single-leg V-sit: One leg raised while the other hovers, loading the hip flexors asymmetrically.
• Alternating V-up: The same V shape reached dynamically, one leg at a time, instead of held.

How Do You Progress the V-Sit?

• Progress leverage before anything else: move from tuck sit to bent-knee V-sit to straight legs, only when the current shape holds for 20 seconds.
• Extend each hold from 10 seconds to 20 to 30 before changing the shape.
• Add a fourth or fifth hold only when three holds at 30 seconds feel steady.
• Slow the lift and lower to three seconds each way to train the entry and exit as well as the hold.

How Should You Program the V-Sit?

Place the V-sit at the end of a calisthenics or core session, after any hanging leg raises or compression work that needs fresh hip flexors. Train it two to three times per week for 3 to 5 holds of 10 to 30 seconds, resting 60 to 90 seconds between holds. Pair it with ahollow holdor with hamstring stretching, since tight hamstrings limit how high the legs can rise.
