Types of Ab Workout Benches

How to adjust sit up bench

They have an adjustable backrest that you set into different levels. Usually, we can choose from 6-8 settings, but better products have 10-12. The settings are somewhere between 10 to 50 degrees.

The main benefit of this type is that you can choose the optimal difficulty for your ab workout. Also, in the long run, it will support your development as you can switch to more difficult degrees from time to time. The best choice if your main goal is to strengthen your abs.


not adjustable

As the name suggests, this sort of ab bench comes with a fixed backrest. Hence, you have to train at the same level of resistance all the time. This type costs less, but the least versatile.

Multi-workout benches

You will see from the reviews below that there are benches with additional functions.

A sit up hyperextension bench features 45 degrees back extension and sit up sections. This way, you can have a more complete core training targeting your entire midsection and even your hams and glutes. The downside of this type is that they support only a few levels for decline bench sit ups.

Other benches - for example, the Fitness Reality Bench - can be used as a weight bench for weight lifting.

How is that possible?

You can set the back pad into flat and decline positions to do such exercises like the bench press. Also, they have a high maximum weight capacity (over 600 pounds) thanks to a robust steel structure.

Of course, multi-purpose benches are more pricey, but they substituted multiple pieces of exercise equipment.

Essential features of decline sit up bench

The size of the board

Most of the benches are made for people who have average height. However, if you are taller than average, you should look for a board with an extended backrest. A short board is not only uncomfortable but also dangerous if your head hits the floor. So, check the size carefully.

The used materials for the frame

Most of the sit up benches are made from heavy-duty steel, so their weight capacity is rather high about 250-300 lbs. That is enough for most of the users. However, if you want to use it as a weight bench, higher capacity is required. Obviously, those more robust ab machines are a bit more expensive, but they are more versatile and gym-quality machines.

The cushion of the board

The thickness of the cushioning is a major factor. If it is not thick enough, it may hurt your back, but the too thick cushion is also not very comfortable. I think 2-3 inch thick foam padding is sufficient.

The number of adjustments

To tell the truth, I do not recommend that equipment that is not adjustable. Sooner or later, you get used to the same training, and you will not be able to give the resistance for your abdominal muscles to grow. So, get an adjustable bench that comes with at least 4 levels, but the more, the better.

Common Problems


Minimal wobbling is inevitable, but it should not be too much.

Tilting and moving can happen for three reasons:

  • You place the bench on an uneven floor. An easy solution is placing a thick rubber mat under it. That usually solves the problem.
  • The other reason is the poor assembly. Check if all the bolts are tight, and all the parts are the right place.
  • The third reasons come from the structure of the product. For instance, the stabilizers are not wide enough, so the bench swings to sides. Or, the equipment is too lightweight.


Typically, you do not have to an expert to put a sit up bench together, but the devil never sleeps. It is not rare that a bolt, a washer, a nut, or another tiny part is missing. Also, do not forget you need at least an adjustable wrench and screwdriver for assembly.

Quick advice: Only tighten the bolts totally when you are ready with the assembly.


The price of an ab workout bench depends on various factors.

A heavy-duty, commercial sit up bench with solid steel construction obviously costs more than a lightweight piece you can get at your local store.

The thickness and durability of the board, the number of adjustments, and the additional functions each mean extra cost.

I'm sure you have heard a million times that what you pay is what you get, but it is true. I know it from my experience. My first adjustable sit up bench was about 30 bucks. After 2 months of painful usage, it found itself in the garbage container.

A reliable item is at least 100 dollars.


Xmark Fitness: This manufacturer has adjustable benches with the most levels. Their high-end ab bench Xmark XM-4416 has 12. These items are comfortable and give excellent training experience.

Fitness Reality: They have one product, the Multi-Workout Abdominal/Hyper Back Extension Bench, which is my personal favorite. Excellent bench for a home gym where size matters.

Sunny Health & Fitness: This manufacturer makes affordable benches with simple features. However, customer reviews are excellent.

Stamina: Their Stamina Pro Ab/Hyper Bench is a top-rated home exercise equipment among ladies.

Marcy: Their Utility Slant Board is the cheapest option, but users like it. I only recommend it for beginners.
