V-up Double Crunch

Instructions

1
Lie flat on your back on a mat with legs extended, arms positioned at sides or crossed over chest, shoulders relaxed away from ears, and core engaged
2
Ensure neutral spine position with lower back slightly touching the mat, feet together or hip-width apart, and neck in neutral alignment with eyes gazing upward
3
Lower both legs with control from the vertical position, allowing hip flexion while maintaining a neutral spine and keeping abdominal muscles engaged to prevent lower back arching
4
Drive legs upward by contracting the rectus abdominis and iliopsoas, returning to the starting position with legs raised to approximately 90 degrees of hip flexion or higher
PRIMARY MUSCLESRectus Abdominis

Overview

When programming for Rectus Abdominis growth, the V-up Double Crunch stands out as a highly efficient Strength choice. Performing this movement with Body weight forces your stabilizer muscles to work in tandem with the primary movers, translating to functional strength and enhanced muscular endurance.

Benefits

  • Promotes balanced muscular development by effectively recruiting the Rectus Abdominis and associated synergists.
  • Allows for a natural movement path that closely mimics functional daily activities.
  • Utilizes Body weight to create sustained mechanical tension, forcing deep muscle adaptation.
  • Acts as a highly scalable Strength movement, perfect for both beginners and elite athletes.
  • Significantly enhances the structural integrity and power of the Rectus Abdominis.

Common Mistakes

  • Losing core tension, leading to poor spinal alignment and reduced power output.
  • Shrugging the shoulders or compensating with secondary muscles rather than isolating the Rectus Abdominis.
  • Failing to achieve a full range of motion, which drastically limits Rectus Abdominis engagement.
  • Using excessive momentum to swing the Body weight rather than controlling the eccentric phase.

Pro Tips

Think about pulling from your elbows rather than your hands to better isolate the Rectus Abdominis and minimize bicep/forearm takeover.

Muscle Anatomy

The primary driver is the Rectus Abdominis. However, the movement also recruits Iliopsoas, Rectus Femoris, Sartorius, Transverse Abdominis to maintain control of the Body weight.

Exercise Variations

  • Dumbbell V-up Double Crunch
  • Cable V-up Double Crunch
  • Banded V-up Double Crunch

Beginner Tips

If you are new to the V-up Double Crunch , focus on mastering the movement pattern with zero weight before adding Body weight.
