GHD Sit-Up — CrossFit Core Technique Guide
BB
By Borja Bes — CrossFit Athlete & Hyrox Finisher
The GHD sit-up is one of the most aggressive trunk-flexion movements used in CrossFit. Performed on a glute-ham developer, it takes the athlete into significant spinal extension before a powerful sit-up back to neutral or above. That long range of motion creates a very potent training effect, but it also means volume must be introduced gradually. In CrossFit, GHD sit-ups are common in competitor programming, gymnastics strength cycles, and skill-development phases for athletes who already tolerate standard AbMat sit-ups comfortably.
Quick answer
The GHD sit-up is one of the most aggressive trunk-flexion movements used in CrossFit. Build GHD Sit-Up with low-fatigue practice first; earn volume only after the required positions and range are repeatable.

Best For, Avoid If, and Scaling
| Best for | Low-fatigue skill development for GHD Sit-Up, plus the specific rectus abdominis and hip flexors capacity needed to make the standard repeatable. |
|---|---|
| Avoid if | Avoid or scale GHD Sit-Up if pain changes the movement or the intended position cannot be controlled. Correct this common fault before adding volume: using high volume too early — soreness and cramping are common when athletes progress too fast. |
| Scaling | AbMat sit-ups, anchored sit-ups, or reduced-range GHD reps. |
How to Do the GHD Sit-Up
1
Set the footplate so the hips sit slightly in front of the pad apex.
2
Start tall with ribs down and feet anchored firmly.
3
Lower under control until the torso extends behind the hips.
4
Initiate the ascent by bracing the trunk and driving the arms forward.
5
Return to upright with control — do not crash into the top position.
Common Mistakes
✕
Using high volume too early — soreness and cramping are common when athletes progress too fast.
✕
Setting the machine too long, which removes control at the bottom.
✕
Falling into lumbar extension rather than controlling the range.
Coaching Tips
✓
Treat GHD sit-ups like a progression, not a default ab exercise.
✓
Start with low reps and full recovery before adding density in WODs.
Scaling Options
Easier / Beginner
AbMat sit-ups, anchored sit-ups, or reduced-range GHD reps.
Harder / Advanced
Tempo GHD sit-ups, weighted sit-ups, or strict leg-extended reps.

Frequently Asked Questions
Why are GHD sit-ups considered risky for beginners?
Because they use a much longer range of motion than floor sit-ups and create high eccentric stress on the abs and hip flexors. Beginners should build capacity with standard sit-ups first, then introduce GHD volume slowly.
