The Dumbbell V-Sit Cross Jab is a dynamic core exercise aimed at targeting the abdominal muscles, with secondary engagement of the hip flexors. This exercise, performed using dumbbells, involves assuming a V-sit position, lifting the legs and torso off the ground to create a V shape. While holding a dumbbell in each hand, the individual alternates twisting the torso to perform cross-body punches, engaging the obliques and rectus abdominis. Additionally, the movement challenges the stability of the core while providing resistance against the weight of the dumbbells, contributing to overall core strength and stability.

How to Perform

  1. Setup: Begin by sitting on the floor with your knees bent and feet flat on the ground. Hold a dumbbell in each hand, with your arms positioned by your sides.

  2. Engage Core: Tighten your abdominal muscles to stabilize your core and maintain a straight back throughout the exercise.

  3. Lift Legs and Torso: Lean back slightly and lift your legs off the ground, simultaneously lifting your torso to create a V shape with your body. Your body should form a roughly 45-degree angle with the floor.

  4. Hold Dumbbells: With your arms extended straight out in front of you, hold the dumbbells at chest height, palms facing inward. This is the starting position.

  5. Perform Cross Jabs: Begin the movement by twisting your torso to the right, simultaneously punching the left dumbbell across your body towards the right side. Keep your arms straight throughout the movement.

  6. Return to Center: Return to the starting position with the dumbbells at chest height.

  7. Alternate Sides: Repeat the movement, this time twisting your torso to the left and punching the right dumbbell across your body towards the left side.

  8. Maintain Control: Move in a controlled manner, focusing on engaging your core muscles to stabilize your body throughout the exercise.

  9. Breathe: Exhale as you perform each punch and inhale as you return to the starting position.

  10. Complete Repetitions: Continue alternating sides for the desired number of repetitions, aiming for a smooth and controlled motion with each repetition.

  11. Lower Legs and Torso: Once you've completed the set, lower your legs and torso back to the starting position, gently placing your feet back on the ground.

  12. Rest and Repeat: Take a short rest between sets if needed, then repeat the exercise for the prescribed number of sets and repetitions.


  1. Begin seated on the floor with knees bent, feet flat, holding a dumbbell in each hand.

  2. Engage core muscles to stabilize and lift legs and torso, forming a V shape.

  3. Hold dumbbells at chest height with arms extended, palms facing inward.

  4. Alternate twisting torso to right and left, punching dumbbells across body.

  5. Maintain straight arms and controlled motion throughout the exercise.

  6. Focus on exhaling during each punch and inhaling during return to starting position.

  7. Keep core engaged to stabilize body and prevent excessive rocking.

  8. Ensure proper form by avoiding arching or rounding of the back.

  9. Aim for a smooth, controlled tempo without jerking movements.

  10. Complete desired number of reps while maintaining proper technique for optimal effectiveness.

How Not to Perform

  1. Avoid using momentum to swing the dumbbells, as this diminishes the effectiveness of the exercise and increases the risk of injury.

  2. Do not allow the lower back to round or arch excessively during the movement, as this can strain the spine and detract from targeting the abdominal muscles.

  3. Refrain from hyperextending the neck or shoulders; keep them relaxed and in line with the rest of your body to prevent strain.

  4. Avoid holding your breath; remember to breathe continuously throughout the exercise to maintain energy levels and prevent fatigue.

  5. Do not rush through the repetitions; instead, focus on controlled movements to maximize muscle engagement and minimize the risk of injury.

  6. Avoid overarching or overarching the arms during the punching motion; keep them slightly bent to prevent strain on the elbows and wrists.

  7. Do not let the legs drop or the torso collapse; maintain the V-sit position throughout the exercise to keep the core muscles engaged.

  8. Avoid using excessively heavy dumbbells that compromise form; choose a weight that allows you to perform the exercise with proper technique and control.

  9. Do not neglect the hip flexors; actively engage them to support the movement and enhance stability during the exercise.

  10. Avoid distractions and maintain focus on the mind-muscle connection; concentrate on contracting the abdominal muscles with each punch to maximize effectiveness.


Variations of fitness exercises refer to different ways of performing a specific exercise or movement to target various muscle groups, intensities, or goals. These variations aim to challenge the body differently, prevent plateaus, and cater to individuals with varying fitness levels.

Alternative exercises in fitness refer to different movements or activities that target similar muscle groups or serve the same training purpose as the primary exercise. These alternative exercises can be used as substitutes when the original exercise is unavailable or challenging to perform due to various reasons such as equipment limitations, injuries, or personal preferences.
