When building your home gym, a weight bench can be a key addition, and the REP Fitness AB-5000 Zero Gap Weight Bench does not disappoint. Aside from using a weight bench for your standard bench press, a weight bench can also allow you to perform exercises like dumbbell rowsflyesshoulder presses, and even lower body exercises, like step-ups and split-squats. The AB-5000 stands out from its competitors as it allows for all of this versatility, but doesn’t have the typical gap you may find on other weight benches across the market. 

This bench from REP Fitness features a unique adjustment mechanism that allows the seat to slide, creating zero gap between the pads. You can also add a decline leg roller attachment, which transforms this bench into a full FID (flat, incline, decline) bench. This weight bench comes in five different colors and is rated at 1,000 pounds. If you’re looking for a commercial-grade adjustable weight bench that offers optimal comfort for heavy lifts, the REP Fitness AB-5000 could be for you. 

Main Takeaways

  • The additional leg attachment turns this weight bench into a full FID bench, and offers five seat pad adjustments (-15, 0, 15, 30, 45).

REP Fitness AB-5000 Zero Gap Weight Bench Highlights

The beauty of weight benches is that no matter what level lifter you are, they can be used for anyone’s workouts. The seven back pad adjustments and five seat pad adjustments on the AB-5000 allow for both incline and decline presses (if you opt for the leg roller). The 11-gauge steel frame and thick non-slip padding also make this bench both stable and durable. 

While it is a bit more expensive than some of its competition, the zero gap feature and versatility you get with this product can make the price worth your while. With a total length of 53.5 inches, a seat pad width of 15 inches, and a back pad width of 12.25 inches, you can fit this weight bench in most places in your home — plus, the handle and wheels make it easy to move out of your power rack so you can rep some squats. However, you still need about eight square feet of space, so if you’re living in a small apartment or don’t have much room to spare in your home gym, size is a factor to consider. 

Who Should Buy the REP Fitness AB-5000

  • Anyone looking for a high-stability bench that can support heavy lifts. This bench is rated at 1,000 pounds.
  • Athletes wanting to target their upper and lower chest by incorporating both incline and decline exercises.
  • Folks who dislike the gap you typically find between the seat and the back pad on most benches — this bench’s adjustment mechanism creates zero gap. 

Who Shouldn’t Buy the REP Fitness AB-5000

  • Anyone who is on a budget and doesn’t want to spend $600 on a weight bench — there are options out there for a fraction of the price.
  • Those who are using their piece of equipment primarily as a flat bench do not need all the adjustment features this bench offers.
  • People who do not have the appropriate eight square feet of space for this bench within their home gym set-up.


The AB-5000 comes in two prices that are determined by the color you choose. The metallic black, red, blue, and matte black will cost around $600, while the clear coat option will cost around $680. The attachable leg roller is listed for an additional $110, and you also have the option of buying a wider bench pad for around $90.

If you opt for the accessories, you’re looking at spending anywhere from around $800 to $900 on your bench. While this may seem expensive, there are other options out there that will cost you even more. Since REP Fitness forged this weight bench with 11-gauge steel, it’s meant to last, and it may be the only weight bench you will need to buy for at least a few decades.

Overall Build and Quality

Weighing 110 pounds, the AB-5000 is a very sturdy bench, and there’s no need to be concerned about it tipping over while lifting. In our time with this bench, we could really feel just how sturdy it was and were never worried about it being unstable; it was also hard to ignore the weight of the bench. You can definitely feel the full 110 pounds when moving it around. It’s rated at 1,000 pounds, which means it can even support workouts from powerlifters who likely have a higher threshold. Its 11-gauge steel is comparable to that of equipment you will find in professional gyms, and this bench only has a footprint of eight square feet, which should allow it to fit in most home gyms.


The AB-5000 is as versatile as it gets when it comes to weighted benches. The leg roller attachment allows it to be transformed into a full FID bench, and its multiple angles can help you target specific areas of your chest. The patented adjustment mechanism creates zero gap between the seat and the back pad, which really makes this bench stand out — but, more on the specifics below.


The AB-5000 offers five seat pad adjustments (-15, 0, 15, 30, 45) to go along with seven back pad adjustments ranging from zero to 90 degrees. These are easily adjusted with the pop-pin mechanism. Just pull the pin out then pop it back in at your desired angle to achieve the optimal position for your workouts.

To take advantage of the zero gap between the seat and back pads, simply unscrew the pin, pull it out, and slide the seat to where you want it. This is one of the most unique features that a weight bench could have since you don’t have to deal with the annoying gap on your lower back when doing a bench press, allowing you to feel comfortable.

Leg Roller Attachment

The optional leg roller transforms this bench into a full FID bench. The decline angles offered with the leg roller attachment are beyond what many of REP’s competitors offer, creating more challenging angles for both decline bench and decline sit-ups. However, this attachment will cost you an additional $110.

Laser Cut Degree Markings

REP Fitness features laser engraved numbers on this bench on a stainless steel wear guard. This allows you to quickly and accurately adjust your bench to the precise position you are seeking.


If you are purchasing this bench to pair with a power rack and need to move it in order to squat, you can do so easily thanks to the wheels and urethane grip handle. Since this bench weighs 110 pounds, the wheels are essential to ensure all users are able to maneuver the bench. The wheels are also shielded by metal for added durability.

AB-5000 Handle Placement

In our time with the AB-5000, we did notice that the handle was a little difficult to reach compared to the handle on some competitor benches. That being said, it’s still better than a weight bench with no handle, and we got used to it after a few uses.

Product Specs

Though the dimensions of this bench are fairly small, you’ll still need to map out your available space to ensure you have eight square feet to fit this product in your home. This durable bench pairs an 11-gauge steel build with non-slip vinyl padding that is meant to last as long as the commercial-grade benches you’d find in professional gyms. Plus, it can support athletes of all levels as it is rated at 1,000 pounds. 


The AB-5000 is built from 11-gauge steel, meaning it’s durable enough that it could potentially be the only bench you need to purchase for quite a few decades (if not longer). This steel is comparable to the quality you find in professional gyms, making it one of the sturdiest options on the market. Plus, the front “foot” juts out to the sides and front, which only adds to its stability. 

REP Fitness AB-5000 Padding

The pads are made of non-slip vinyl, so no matter how sweaty you get, they’ll help you stay put — even during those heavier lifts. The padding is also firm enough to support your hard work, but still provides comfort when you’re laying on it.


There are a few different dimensions to consider with this weight bench. The total height when at zero degrees is 17.5″. The total pad length is 53.5” with a back pad of 38.5” and a seat pad of 15” in length, respectively. The back pad is 12.25” in width, the wider option is 14”, and the seat is tapered from 12″ to 8″ in the front. The total footprint of the AB-5000 is eight square feet, which is fairly small but not negligible — especially if you are living in a small studio apartment. 

Weight Capacity

The REP Fitness AB-5000 is rated to support up to 1,000 pounds including your body weight. This is above average for a weight bench, which you will find reflected in this product’s price tag. 


REP Fitness features a 10-year warranty on the bench frame and one year on the pop-pins.

Final Word

The REP Fitness AB-5000 features a high-quality 11-gauge steel build with a weight limit of 1,000 pounds. This is a great option for both novice and expert lifters, and anyone looking to utilize the multiple incline and decline angles it offers. The five different seat pad adjustments and seven different back pad adjustments featured on this bench offer the ability to switch up your workout to prevent your body from becoming accustomed to the same range of motion. What really makes this weight bench stand out is the zero-gap adjustment — without the awkward space that most benches have between the seat and back pads, you can be completely comfortable while lifting.

We did notice that the handle on the front of the bench that allows you to move it around your gym was a little difficult to reach compared to some competition, but it didn’t prove to be much of a problem after a few uses. While this bench is also a bit pricey, and you do have to purchase an additional leg roller attachment to perform decline exercises, the AB-5000’s versatility and lasting build may make it the last weight bench you’ll ever need (or want) to purchase — at least for a few decades.


What is the zero-gap feature on the REP Fitness AB-5000?

This zero-gap bench has an adjustable seat that creates zero gap between the seat and back pad. This allows users to use their bench as a flat bench more comfortably.

How much does the REP Fitness AB-5000 cost?

The final price tag of this bench is determined by your color choice, and whether or not you want to add the leg roller attachment for around $110 or a wider back pad for about $90. The metallic black, matte black, red, and blue options will run you around $600, while the clear coat option is about $680. So, you’re looking at spending anywhere from $600 to about $900 on this bench.

How long will the REP Fitness AB-5000 last?

On average, a good weight bench can last you up to 20 years. Besides normal wear and tear on the pads, you really shouldn’t have to worry about much other than the adjustable mechanism becoming worn over time.
