Oblique V-Ups: Step-by-Step Guide, Benefits, and Variations

By Hart 7 min read

Oblique V-ups are an advanced core exercise performed by simultaneously lifting the torso and legs from a side-lying position, forming a 'V' shape to target the obliques and core muscles.

How Do You Do Oblique V-Ups?

The oblique V-up is an advanced core exercise that primarily targets the external and internal obliques, along with the rectus abdominis and hip flexors, by simultaneously lifting the upper and lower body towards each other in a side-lying position.

Understanding the Oblique V-Up

The oblique V-up is a dynamic, multi-joint core exercise designed to challenge the entire abdominal wall, with a particular emphasis on the oblique muscles responsible for trunk rotation and lateral flexion. Unlike traditional V-ups that primarily work the rectus abdominis in a sagittal plane, the oblique V-up introduces a rotational and lateral component, making it an excellent exercise for developing comprehensive core stability and strength.

Muscles Engaged

To effectively perform and understand the oblique V-up, it's crucial to know which muscles are actively involved:

  • Primary Movers:
    • External Obliques: Responsible for trunk rotation and lateral flexion.
    • Internal Obliques: Work synergistically with the external obliques for rotation and lateral flexion.
    • Rectus Abdominis: Assists in spinal flexion (bringing the chest towards the hips).
    • Hip Flexors (Iliopsoas, Rectus Femoris): Crucial for lifting the legs.
  • Stabilizers:
    • Transverse Abdominis: Provides deep core stability.
    • Quadratus Lumborum: Assists in lateral flexion and stabilization of the lumbar spine.
    • Gluteus Medius/Minimus: Provide stability to the hip during the leg lift.

Step-by-Step Guide: Performing the Oblique V-Up

Mastering the oblique V-up requires control, coordination, and a strong core foundation. Follow these steps for proper execution:

  • Setup:
    • Lie on your side: Begin by lying on your side on a mat, with your bottom arm extended straight overhead on the floor. This arm provides stability and acts as an anchor.
    • Stack your legs: Your legs should be stacked one on top of the other, fully extended.
    • Top arm position: Place your top hand behind your head, with your elbow pointing towards the ceiling. Alternatively, you can extend your top arm straight out in front of you, parallel to your body, for balance.
    • Engage your core: Before initiating movement, gently brace your abdominal muscles to stabilize your spine.
  • Execution (Concentric Phase):
    • Simultaneous lift: In one controlled motion, simultaneously lift your torso and your legs off the floor, bringing them towards each other in a "V" shape.
    • Target the obliques: Focus on contracting your obliques to initiate the lift, feeling the side of your waist shorten. Your top elbow should aim towards your top hip or knee.
    • Maintain straight legs: Try to keep your legs as straight as possible throughout the movement, though a slight bend in the knees is acceptable if necessary to achieve the V-up shape.
    • Reach your peak: Lift as high as you comfortably can, aiming for your body to form a "V" shape, balanced on your hip.
  • Execution (Eccentric Phase):
    • Controlled descent: Slowly and with control, lower your torso and legs back down to the starting position. Resist the urge to let gravity drop you.
    • Maintain tension: Keep your core engaged throughout the entire lowering phase to maximize muscle activation and prevent injury.
  • Breathing:
    • Exhale on exertion: Breathe out as you lift your torso and legs (concentric phase).
    • Inhale on descent: Breathe in as you slowly lower back down (eccentric phase).
  • Repetitions and Sets:
    • Aim for 8-15 repetitions per side, for 2-3 sets. Focus on quality of movement over quantity.

Common Mistakes to Avoid

Improper form can reduce the effectiveness of the exercise and increase the risk of injury. Be mindful of these common errors:

  • Using Momentum: Jerking your body up rather than using controlled muscle contractions. This reduces muscle activation and increases spinal stress.
  • Arching the Lower Back: Allowing your lower back to arch excessively, particularly during the lowering phase, can strain the lumbar spine.
  • Pulling on the Neck: If your hand is behind your head, avoid pulling on your neck to lift your head. The movement should come from your core.
  • Insufficient Range of Motion: Not lifting high enough or lowering fully. Aim for the full V-up shape and a controlled return to the starting position.
  • Not Engaging Obliques: Relying too much on hip flexors or rectus abdominis instead of actively contracting the side abdominal muscles.
  • Uneven Sides: Neglecting to perform an equal number of repetitions on both sides, which can lead to muscular imbalances.

Benefits of Incorporating Oblique V-Ups

Adding oblique V-ups to your routine can yield several significant benefits:

  • Enhanced Core Strength: Develops robust strength in the entire abdominal wall, particularly the often-underutilized oblique muscles.
  • Improved Rotational Stability: Crucial for everyday movements, athletic performance (e.g., throwing, swinging), and preventing injuries from twisting motions.
  • Better Posture: A strong core, including the obliques, helps stabilize the spine and pelvis, contributing to improved upright posture.
  • Increased Body Control and Coordination: Requires precise control over both upper and lower body movements simultaneously.
  • Functional Movement: Mimics movements used in sports and daily life that involve twisting and bending.

Variations and Progressions

To adjust the oblique V-up to your current fitness level, consider these modifications:

  • Easier Variations:
    • Bent-Knee Oblique V-Up: Keep your knees bent as you lift, reducing the lever arm and making the exercise less challenging.
    • Single-Leg Oblique V-Up: Lift only the top leg while keeping the bottom leg on the floor, focusing more on the upper body crunch.
    • Supported Oblique V-Up: Use your top hand on the floor in front of you for additional balance and support during the lift.
  • Harder Progressions:
    • Weighted Oblique V-Up: Hold a light dumbbell or weight plate in your top hand or between your feet (if capable) to increase resistance.
    • Extended Arms/Legs: Keep both arms extended overhead or both legs completely straight throughout the entire movement for increased leverage challenge.

Who Should Consider Oblique V-Ups?

The oblique V-up is generally suitable for:

  • Intermediate to Advanced Fitness Enthusiasts: Individuals with a foundational level of core strength.
  • Athletes: Especially those involved in sports requiring strong rotational power (e.g., golf, tennis, baseball, martial arts).
  • Individuals Seeking Core Challenge: Those looking to diversify their abdominal routine beyond traditional crunches and planks.

It may not be suitable for beginners or individuals with acute lower back pain, hip flexor issues, or shoulder problems.

Safety Considerations and When to Consult a Professional

  • Listen to Your Body: Never push through sharp pain. Discomfort is normal with muscle exertion, but pain is a warning sign.
  • Proper Form Over Quantity: Always prioritize perfect form over the number of repetitions. Incorrect form is less effective and increases injury risk.
  • Warm-Up Adequately: Prepare your core and hip flexors with light cardio and dynamic stretches before attempting oblique V-ups.
  • Progress Gradually: If the full oblique V-up is too challenging, start with easier variations and gradually build strength.
  • Consult a Professional: If you have pre-existing conditions (e.g., spinal issues, hip problems, recent surgery), or if you experience persistent pain during or after the exercise, consult with a qualified healthcare professional or a certified physical therapist/trainer. They can provide personalized advice and modifications.
