Walk into any CrossFit gym and you'll find a padded bench with a footplate sitting against the wall. Most people walk right past it, or assume it's a machine for advanced athletes. It's called the GHD, and it's one of the most valuable tools we have for building a strong, durable midline.
At CrossFit AFK in Mason, MI, the GHD shows up in warm-ups, accessory work and workouts. Members from Holt, Mason and Lansing use it to strengthen the back side of the body, build control through the trunk, and protect the lower back for the long haul.
Yes, the GHD is for beginners too. It just has to be introduced the right way.
GHD stands for glute-ham developer. The name comes from the glute-ham raise, a hamstring exercise the machine was originally built for. In CrossFit, we use it for something broader: midline stabilization.
CrossFit defines core strength as the ability to keep the spine and pelvis locked together so force travels from the hips to the hands without leaking. That is the same skill that keeps your back flat when you pick up a heavy box and keeps you upright when you carry groceries up the stairs. CrossFit calls the GHD essential to that work (CrossFit).
The GHD trains both sides of the trunk:
We use the GHD for four main movements. Each one has its own article with full instructions and every scaling option.
The position of the pad decides which movement you're doing. For hip extensions, the pad sits under your upper thighs so your hips can fold. For back extensions, the pad slides forward to support your pelvis so only the spine moves. Your coach will help you set it every time until it becomes second nature.
The GHD isn't about building a six-pack. It's about building a trunk that holds up under real-life demands.
Every time you bend to lift a laundry basket, pick up a child, shovel snow or load a car, your hips and spine have to work together. GHD training teaches you to control those positions on purpose, so your body knows how to hold them when it matters.
CrossFit founder Greg Glassman argued that most people are weak at hip flexion and that hip and back extension work is indispensable to lower-back health (CrossFit). That's why we train both sides of the body.
The GHD is potent. A small dose goes a long way, and the soreness from doing too much too soon shows up a day or two later. That's true for brand-new members and for fit athletes returning after time off.
At CrossFit AFK, we follow the same order CrossFit teaches: mechanics, then consistency, then intensity.
You'll see GHD work in warm-ups before you see it in a workout. Warm-up reps are the practice; the workout is the dose.
Scaling is not making the workout easier. Scaling is how we give each person the right dose of the same stimulus.
Every GHD movement can be scaled by range of motion, reps, lever length or load. If you don't have a GHD, or you're not ready for one yet, every movement has an alternative that trains the same pattern:
Each movement article lists every option, from beginner to advanced.
Once the main four movements are solid, the GHD opens up a whole menu of options: glute-ham raises, reverse hypers, side extensions, weighted variations and isometric holds. We cover those in Beyond the Main Four: Additional GHD Exercises.
The GHD isn't reserved for advanced athletes. With good coaching and appropriate scaling, it's one of the best tools we have for building a strong, capable body for life.

GHD stands for glute-ham developer. It's sometimes called a glute-ham bench or a Roman chair.
Yes, when it's introduced gradually. Beginners start with hip extensions and short-range sit-ups, and every GHD movement can be scaled.
The GHD works the glutes, hamstrings and spinal muscles in the extension movements, and the abdominals, hip flexors and quads in the GHD sit-up.
Yes. Wall extensions, good mornings, glute bridges and floor sit-ups all train the same patterns.
The GHD sit-up works the abs through a long range of motion. Too many reps too soon causes significant soreness, so we build volume gradually. If you ever notice dark, cola-colored urine after a workout, seek medical care right away.
