REP Fitness AB-5000 Zero Gap Weight Bench Review

When building your at-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 rows, flyes, shoulder presses, and even lower body exercises like step-ups and bench split-squats. The REP Fitness AB-5000 Zero Gap Weight Bench 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 sliding bench seat here is a great find, creating zero gap between the seat and back pad at all angles.
  • REP’s commercial grade 11-gauge steel can withstand weights up to 1,000 pounds.
  • The additional leg attachment turns this weight bench into a full FID bench, and offers five seat pad adjustments (-15, 0, 15, 30, 45).

The REP Fitness AB-5000 Zero Gap Weight Bench stands out from its competitors as it doesn’t have the typical gap you may find on other weight benches across the market. Plus, it has seven back pad adjustments and five seat pad adjustments.

REP Fitness AB-5000 Zero Gap Weight Bench Highlights

The beauty of weight benches is that no matter what level of weight lifter you are, they can be a great addition for anyone looking to take their workouts to the next level. The seven back pad adjustments and five seat pad adjustments on the AB-5000 allow for both incline and decline presses. The 11-gauge steel frame and thick non-slip padding make this bench both stable and durable. 

While it is a bit more expensive than 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”, a seat pad width of 15”, and a back pad width of 12.25”, you can fit this weight bench in most places in your home — plus it can work in tandem with most power racks. 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 Zero Gap Weight Bench

  • 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 Zero Gap Weight Bench

  • Anyone who is on a budget and doesn’t want to spend close to $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 at three prices that are determined by the color you choose. The metallic black will cost around $579; red, blue, and matte black will cost around $599; and the clear coat option will cost around $679. The attachable leg roller is listed for an additional $109.99, and you also have the option of buying a bench pad to add even more width to your bench for just under $80.

If you opt for the accessories, you’re looking at spending anywhere from $700 to $900 for your bench. While this may seem expensive, there are other options out there that will cost you over $1,000. REP Fitness forges their products with 11-gauge steel, meaning this equipment is 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 125 pounds, the AB-5000 is a very sturdy bench — there’s no need to be concerned about it tipping over while lifting. 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 — simply unscrew the pin, pull it out, and slide the seat to where you want it. Then, just push the pin back in, and you’re good to go. 

You can also rest assured that as you adjust the bench, the adjustment mechanism will allow the seat to slide, creating zero gap between the back and the seat. This can help ensure optimal comfort during lifts.

Leg Roller Attachment

The optional decline 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 that would typically require an additional piece of equipment. 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 urethane grip handle and wheels. Since this bench weighs 125 pounds, the wheels are essential to ensure all users are able to maneuver the bench. The wheels are also shielded by metal that can double as a platform for your spotter.

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 is a durable bench — it’s made with 11-gauge steel and 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. 

The pads are made from non-slip vinyl, so no matter how sweaty you get, they’ll help you stay put — even during those heavier lifts. 


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 seat pad of 15” in length, respectively. The back pad is 12.25” in width, the wider option is 14”, and the seat width is 12” with the ability to taper to 8”. 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 is highly rated and for good reason. It has a high-quality build and a zero-gap feature you don’t find from much of its competition. If you are an athlete looking to utilize incline and decline features on a weight bench or wanting to focus on decline sit-ups, this bench is a great option for you.

The five different seat pad adjustments and seven different back pad adjustments offer the ability to switch up your workout, and 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. While this bench is a bit pricey and you do have to purchase an additional leg roller attachment to make full use of the decline option here, 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.
