The core is a major muscle group in the human body. It is responsible for improving your balance and stability, eliminating back pain, achieving an upright posture, and many more. 

It may not be so evident, but we use our core strength for a lot of mundane everyday things such as pulling, pushing, carrying, and gaiting.

On the surface of the core muscles are the abdominal muscles or what we fondly call “abs”. Here you can find the lower abs, obliques, upper abs, serratus, and transverse abdominus. Aside from playing major roles as your body’s main stabilizers, having a nice set of abs helps achieve a well-balanced physique.

Our Editor’s Pick, the Bowflex 5.1S Stowable Bench, can very well help you achieve all of these goals. This particular sit up bench is an easy favorite for us, given its complete set of features and astounding 600 lbs weight capacity, all under a reasonable price.

In this article, we focus on reviewing 10 best sit up benches altogether in various categories – from the most affordable to most splurge-worthy to most beginner-friendly, and more. 

Each one is designed to provide stability and safety you will need in performing core exercises that will help you achieve functional, healthy, and aesthetic rock-hard abs in 2022.

Buyer’s Guide: Choosing the Best Sit Up Bench

Adjustability and Versatility

A standard sit-up bench has at least 4 back support adjustment settings and 3 seat settings. Some sit-up benches, such as the XMark Utility Slant Board, offer 12 levels of decline adjustment, which gives you plenty of exercises to try out.

Maximum User Weight

According to our research, the typical user weight limits on the sit-up benches are 250 lbs, 300 lbs, 600 lbs, and 1,000 lbs. Sit-up benches with a 250 lbs weight limit are best for smaller individuals, while a maximum user weight capacity of 1,000 lbs, such as seen on the Rep Fitness FID, is best for heavy-weight lifters that carry plenty of muscle mass.

Material, Construction, and Dimension

The standard material combinations for ab benches are alloy steel (mainframe), vinyl (padding or cushion), and foam (rollers and leg support). Some sit-up benches are bulkier and heavier than others as they provide more support for non-abs exercises. Smaller sit-up benches are either built for shorter individuals or designed for space efficiency and portability.

Price

We recommend looking for a sit-up bench that costs at least $100 and provides the basic, long-term functions you’ll need. This is a good price range that won’t rip your wallet and is not suspiciously cheap, either. For options, check out Marcy Utility Slant Board, FLYBIRD Adjustable Bench, LeikeFitness Adjustable Weight Bench, and Marcy Multi-Purpose Bench.

Frequently Asked Questions

Reverse crunches, leg lifts, and other famous ab exercises are suitably done on the floor. However, if you want to take it up a notch and find better angles to hit your obliques and ab muscles and feel more burn, a decline sit-up bench is a sound investment for your long-term fitness using affordable exercise equipment.

Choose the best sit-up bench for you by looking at your budget, current fitness level, future goals, body weight, and accessory needs. 

Some noteworthy questions to ask yourself: Can I afford a more expensive bench if given the availability? Do I plan on using the bench for non-abs exercises? How much floor space am I willing to allocate for a sit-up bench?

Ab benches are a great investment to kickstart your abs program. With a sit-up bench, you have better access to more core exercises that are typically hard to perform only on the floor. In fitness reality, a good sit-up bench will help you a great deal in terms of your coordination, balance, and strength.

Sit-up benches are also called decline ab bench based on the positioning. The board itself could also be referred to as a slant board because of its permanently slanted angle.
