A Roman chair (otherwise known as a hyperextension machine) is a finer form multi functional adjustable weight bench used to tone the lower back, legs, and core. A popular exercise that can be used on one of these machines is a Roman chair sit up, which helps strengthen the abdominal muscles and stabilizer muscles in the core.
Let’s dive into how to do Roman chair sit ups, their benefits, and more!
But before we do, we’d like to show you the top 3 choices available online in case you want to purchase one for your home:
The Benefits of Doing Romanian Chair Sit Ups
One of the biggest Roman Chair sit up benefits is that similar to traditional sit ups/crunches, this exercise helps tone your abdominal muscles in an all-encompassing way. By developing your abs in a way that forces you to engage your entire core, these exercises can help give you a stronger and more stable midsection like few other ab exercises could.
This is vital, as your core is responsible for keeping you upright and steady to prevent you from wobbling when you move around. In fact, former professional bodybuilder Arnold Schwarzenegger himself incorporated this exercise into his regular workout routine to build up and tone the abs that he is well known for.
Additionally, Arnold’s Roman chair sit ups target your hip flexors, glutes, and quads since they help you maintain proper form when performing this exercise.
The hip flexor muscles allow you to move your legs around, the quads allow you to bend your knees, and the glutes allow you to stay upright when you need to be. When combined with a strong core, these lower-body muscles can help you move, and excel, through various kinds of physical activity.
Downsides of Doing Roman Chair Sit-Ups
Unfortunately, the Roman chair sit ups Arnold Schwarzenegger did for his abs are too difficult for just anyone to do, especially beginners. The mechanics of a Roman chair sit up machine, which involves lowering yourself from a seated position to a reclined position, can exert too much pressure on your lower back and lead to hyperextension. This can worsen any lower back pain that someone might currently be experiencing.
Roman chair sit ups can also add additional strain to your hip flexors. A counter-strain injury can occur as a result of trying too hard to maintain proper form, which can negatively affect your gait once you step off the machine by causing you to limp as you move.
These risks, however, mainly occur if you use the machine incorrectly and with improper posture; or if you lack the necessary strength to pull it off. If you don’t already have strong abs from doing other core-strengthening exercises, you should not be using a Roman chair sit up bench this way.
Different Roman Chair Sit-Up Techniques
One variation of a Roman sit up is a weighted Roman chair sit up, which is essentially the same as a normal Roman chair sit exercise but with added weights.
As you move your upper body, you hold a small weight of no more than about 10 pounds in front of your chest. By adding an additional load of weight, you would be forcing your core to work harder as you move, which can aid in total-body stabilization.
Abdominal Muscles Targeted
A Roman chair sit up primarily targets the muscles of the abdominal region, specifically the rectus abdominis and the obliques. Here’s a breakdown of the muscles involved:
- Rectus Abdominis: This is the primary muscle worked during a sit-up. It’s the long muscle that runs vertically along the front of your abdomen and is often referred to as the “six-pack.”
- Obliques (Internal and External): The obliques are located on the sides of your abdomen. There are internal and external obliques, and both are involved in different aspects of the sit-up. They help with rotation and lateral flexion of the trunk.
- Hip Flexors: The hip flexors, including muscles like the iliopsoas, are involved in bringing your torso upward. These muscles connect the thigh bone to the spine and play a crucial role in hip flexion. The iliopsoas is a group of muscles located in the hip region, and it is actually composed of two muscles:
- Psoas Major: This muscle originates from the lumbar vertebrae (specifically, the bodies of T12 and L1-L5) in the spine and descends down through the pelvis to attach to the lesser trochanter of the femur. The psoas major is a powerful hip flexor.
- Iliacus: The iliacus muscle originates from the iliac fossa of the pelvis and also attaches to the lesser trochanter of the femur. Like the psoas major, the iliacus is a hip flexor.
- Erector Spinae: These muscles run along your spine and are responsible for spinal extension. They play a supportive role during the sit-up, helping to stabilize the spine.
It’s essential to perform Roman chair sit ups with proper form to maximize the engagement of these muscles and minimize the risk of injury. Ensure controlled movements and avoid using momentum to lift your torso.
Different Types of Roman Chair Machines
If you want to do Roman chair sit ups at home, keep in mind that there are two main types of Roman chair machines you can buy, which are differentiated by the angle that the support pad is at (and, by extension, the angle of hyperextension of the back that a certain Roman sit up bench allows for).
45-Degree Angle Machine
Using a machine that allows for 45-degree hyperextension is considered to be the safer and easier of the two options because the smaller angle requires less core strength to maintain proper form as you move.
The support pad being at 45 degrees also makes it easier for you to stay upright, granting you more control over the difficulty or intensity at which you want to perform the exercise.
90-Degree Angle Machine
Using a machine that allows for 90-degree hyperextension is considered to be the more effective of the two options because the larger angle requires significantly more core strength to maintain proper form and support your body as you perform the exercise.
This means, however, that those who either lack an already-existing stable core or are just getting started on a Roman chair machine should not use a 90-degree Roman chair machine.
Other Types of Exercises to Target Your Abs
Whether or not you’re able to afford a Roman chair machine, simply struggle to find a place in your home to put one, or maybe you just don’t want to risk hurting yourself doing such a challenging exercise, there are other exercises you can do to target your Abs before hopping onto a Roman chair sit up bench for a stronger core:
While this popular isometric exercise may still be too difficult for some due to the massive amount of endurance needed to hold the position, it’s still a much simpler and safer option than using a Roman chair. Not only do planks help strengthen your muscles, but they can also help increase your flexibility and endurance, which can be important in various physical activities.
Russian twists affect almost the same muscle groups as a Roman chair sit up: your obliques, abdominal muscles, and hip flexors. The only difference is that Russian twists are arguably much simpler due to the fact that they don’t require any exercise equipment.
- Sit on the ground with your knees bent and feet flat.
- Lean back slightly and lift your feet off the ground.
- Twist your torso to one side, bringing your hands or a weight to touch the ground beside you. Alternate sides.
Mountain climbers are another effective exercise that targets the same abdominal and leg muscles as a Roman chair sit up. However, mountain climbers also have the unique advantage of strengthening your arm and shoulder muscles, as well. In some cases, these can even help with losing weight due to their higher intensity.
Different Types of Sit-Ups to Try
Traditional sit-ups may be too boring, while Roman chair sit ups may be too difficult. If that is the case, there are many ways to spice it up without needing a Roman chair:
- Lie on your back with your knees bent and feet flat on the ground.
- Place your hands behind your head or cross them over your chest.
- Engage your core and lift your upper body toward your knees.
- Lower your upper body back down to the starting position.
- Similar to the basic sit-up but with a shorter range of motion.
- Lift your upper body just a few inches off the ground, focusing on contracting the abdominal muscles.
- Lie on your back with your hands at your sides or under your hips.
- Lift your legs, bringing your knees toward your chest while lifting your hips off the ground.
- Lie on your back with your hands behind your head.
- Lift your legs off the ground and pedal them in a bicycle motion while bringing your opposite elbow toward your knee.
- Lie on your back with your hands under your hips.
- Lift your legs toward the ceiling, keeping them straight, and lower them back down without letting them touch the ground.
- Sit on the ground with your legs extended and lean back slightly.
- Lift your legs and upper body simultaneously, forming a V shape with your body.
- Perform a regular sit-up, but twist your torso to one side as you come up, aiming to touch your elbow to the opposite knee.
- Alternate sides with each repetition.
