Sometimes the most brutal tests of strength aren’t about movement they’re about holding on. The dead hang is one of the simplest, most effective ways to develop raw grip strength, shoulder health, and full-body tension.

In this challenge, we’re not asking you to pull. Just hang. For 100 seconds. That’s it.

But don’t be fooled. This challenge will test your willpower, your breathing, your pain tolerance, and your patience all while building the kind of foundation that pays off in almost every other upper-body movement.

“If you can’t hang from a bar, you’ve got no business pulling yourself over one.” — RB100.Fitness


Challenge Format

  • Target: 100-second dead hang
  • Position: Full extension, feet off ground, grip on standard pull-up bar
  • Form: Shoulders slightly active (not passive), core braced, legs straight or tucked

You can complete this in:

  • One unbroken hang (if possible)
  • 2 × 50 seconds
  • 4 × 25 seconds with short rest

Why This Works

The dead hang is a compound isometric hold that hits:

  • Forearms and hands (grip and endurance)
  • Shoulders and scapula (mobility and stability)
  • Core muscles (anti-extension control)
  • Spine and ribs (decompression and posture)

It’s used in gymnastics, climbing, OCR, calisthenics, and even rehab because hanging is something humans are built to do.


Technique Tips

  • Use a slightly wider than shoulder-width grip
  • Engage lats slightly to avoid shoulder impingement
  • Breathe deeply to stay calm under tension
  • Use chalk or straps only if needed challenge yourself raw if safe
  • Don’t swing or rotate stillness is the goal

Progressions & Variations

  • Beginner: 4 × 25s holds, or hang with toes lightly supported
  • Intermediate: Aim for 2 × 50s or 1 × 100s
  • Advanced: Add a weighted vest or switch to one-arm hang intervals
  • Optional Superset: Combine with #75: Toes-to-Bar or #73: Plank Reaches

Use this as a finisher, a warm-up, or even part of your grip training block. You’ll be shocked at how effective it is over time.
