V-Up

The V-Up is an intermediate bodyweight core exercise that simultaneously targets the upper and lower abdominal muscles by folding the body into a distinct 'V' shape. This movement builds explosive core strength, improves hip flexor control, and enhances total body coordination.

How Iridium Helps

Because the V-Up places high demand on both the core and lower back, the AI closely monitors your rep velocity and RPE to detect fatigue-induced form breakdown. If your performance metrics dip, the app can instantly recommend a regression like the Tuck Crunch to protect your lumbar spine. Furthermore, by integrating your sleep and recovery data, the AI ensures this high-intensity core movement is programmed only when your central nervous system is sufficiently recovered.

Form Cues

Do
  • Start with your lower back pressed firmly into the floor
  • Lift your legs and torso simultaneously
  • Keep your legs as straight as flexible allows
  • Reach your fingertips toward your toes at the peak
  • Lower your body slowly back to the start with control
Don't
  • Don't swing your arms to generate momentum
  • Don't let your lower back arch off the floor at the bottom
  • Don't pull on your head or strain your neck
  • Don't drop your legs quickly to the floor

Common Mistakes

  • Using momentum instead of muscle tension
  • Arching the lower back at the starting position
  • Bending knees excessively to reduce leverage
  • Straining the neck forward
  • Descending without controlling the eccentric phase

Muscles Worked

The V-Up is highly effective because it requires the rectus abdominis to contract from both ends simultaneously, maximizing engagement of the entire abdominal wall. It also heavily recruits the hip flexors to lift the legs and requires deep stabilizer muscles to maintain balance at the apex of the movement.
