Abdominal training in professional settings requires equipment that goes beyond the crunch: GHD machines, ab rollers, suspension bands and specialised benches to develop core strength, stability and control in a progressive and measurable way.

Abs: the Sidea routine
When it comes to professional core training, the simple crunch on a mat is only a small part of the picture. Abdominal training — understood as the development of the anterior trunk muscles, the hip flexors and the postural chain — requires equipment that allows for variations in angle, load and body position. The seven products in this selection span different categories: from GHD benches and sissy squats from functional training equipment to support accessories designed to complement existing equipment in the gym or home gym.
Who is abdominal training for?
The obvious answer is: for everyone. The useful answer is more nuanced.
Strength and conditioning coaches working with power sports — alpine skiing, weightlifting, combat sports — use the GHD machine to develop controlled lumbar flexion and eccentric abdominal strength in positions that cannot be achieved on the floor. The GHD back extension and the GHD sit-up are exercises featured in many strength training programmes, including those from StrongFirst and CrossFit.
For CrossFit boxes, the GHD is almost a must-have piece of equipment: the GHD sit-up is a movement featured in official WODs and benchmarks. Having a stable piece of equipment, with adjustable support and high-quality padding, makes all the difference to athletes’ lower back safety.
Personal trainers who work in a gym or who design home gym For experienced clients looking for compact, multi-purpose equipment: the abdominal suspension band or the GHR ab roller take up very little space and offer a wide range of exercises, from core stability to hamstring training.
Home gym enthusiasts with an intermediate to advanced level of fitness will find that the equipment in this selection offers a higher standard than consumer-grade products, without requiring the floor space or facilities of a commercial gym.
How to choose equipment for abdominal exercises
The first criterion is progression. A useful piece of equipment must allow you to increase the load, change the angle of the exercise or move on to more complex variations over time. A generic support cushion does not offer this progression; a GHD machine with precise adjustment of the pelvic position does.
The second criterion is the specificity of the movement. The abdominal muscles work during flexion (GHD sit-ups, crunches on a decline bench) and during anti-extension (ab roll-outs with core wheel or ab roller), anti-rotation exercises and isometric stabilisation exercises (plank on a suspension band, fallout). Choosing a piece of equipment means deciding which movement pattern you wish to prioritise.
The third criterion is suitability for the setting. A professional gym-grade GHD machine differs in size, weight and mechanical strength from a portable ab roller. If you’re setting up a CrossFit box, the GHD bench is an essential purchase. If you’re working in a 30-square-metre studio, the abdominal suspension band is probably more versatile.
Finally: the quality of the materials matters. The padding on GHD benches is a critical factor — a cushion that sags after just a few weeks of intensive use compromises both the athlete’s posture and safety. Similarly, a suspension band must have attachments and stitching designed to withstand repeated dynamic loads.
Sidea abdominal products
The selection is divided into three distinct functional groups.
GHD benches and lower back exercise equipment: the 9120 GHD Bench — Glute Ham Developer is the professional bench par excellence, used for GHD sit-ups, back extensions and hip extensions. The 9123 GHD & Sissy Squat — The Hamstring Bench combines the functions of the GHD machine with the sissy squat, adding a new exercise focus for the quadriceps and offering dual functionality in a single piece of equipment. Both belong to the category Strong fitness training, a specific reference to the context of use.
Ab rollers and suspension training: the 9013/1 GHR — Glute Hamstring AB Roller is a compact piece of equipment that targets lumbar anti-extension, one of the most effective exercise patterns for developing genuine strength in the deep abdominal muscles. The Abdominal Suspension Bands (model 2094 and version Outrace (OR2094) are suspension training tools that enable exercises such as the fallout, pike, body saw and advanced variations, offering a progressive load profile that is difficult to replicate with other equipment.
Accessories and supports: the 9023/2 GHR Padding is a replacement part and upgrade specifically designed for GHD structures, ensuring comfort and safety over time. The 1000 Support Cushion is a versatile cushion that can be used in a variety of contexts, such as functional training and as a support for floor exercises.

Domande frequenti - Addominali
-
The GHD sit-up engages the abdominal muscles across a full range of motion, from lumbar hyperextension through to full trunk flexion. This works the abdominal muscles even during the eccentric phase, which the classic crunch does not achieve. It is a more intense exercise that requires a gradual progression, particularly for those with no experience of lumbar flexion on a GHD bench.
-
Not in the full version performed whilst standing or kneeling on a smooth floor. The ab rollout requires good lumbar anti-extension strength: if the back rounds during the movement, there is a high risk of lumbar strain. You typically start with partial variations or from a position with your knees on the floor, gradually increasing the range of motion.
-
The Sidea Abdominal Suspension Bands require a stable anchor point: a pull-up bar, a multi-purpose rack or a wall-mounted structure. They are not standalone pieces of equipment. In a gym or CrossFit box, finding an anchor point is rarely a problem. In a home gym, you need to check that the attachment point is rated for dynamic loads.
-
A GHD bench allows for at least six main exercise patterns: GHD sit-ups, GHD back extensions, GHD hip extensions, combined GHD hip and back extensions, Nordic curls (with modification), and hollow body variations. Some trainers also use it as a support for lateral stability exercises. It is one of the pieces of equipment offering the best balance between space requirements and variety of movements.
-
The Outrace version (OR2094) is designed to integrate with Outrace rack systems and modular structures, featuring specific fixings compatible with the range’s mounting system. The standard 2094 version is designed for universal use, with attachments to existing bars or structures. The choice depends on the infrastructure already in place in the gym.
-
In most strength training programmes — including those from StrongFirst — the core is specifically trained 2–3 times a week, often as a complement to the main sessions focusing on squats, deadlifts and presses. The frequency varies depending on the programme’s total volume: sessions that are too close together compromise recovery and reduce the effectiveness of stability exercises.
