REP Fitness adjustable benches

With REP's various adjustable benches, it can feel overwhelming to pick the right one. 
 
Each bench is different, with various combos of size, weight capacity, pad angles, adjustment mechanisms, style, and more. Benches range from lightweight (70lbs) to sturdier (131lbs); from 4-gauge steel to 14; and from budget-friendly to high-end. 
 
But you don’t need to get in a shopping workout before getting in your actual workout. Here’s a quick guide to navigate REP's adjustable benches (that’s what the “AB” in the name stands for): the AB-3000 2.0, AB-3100AB-5100, AB-5200, AB-5200 2.0, the Nighthawk™, and the BlackWing adjustable bench. 
 
Note: All of Rep’s adjustable benches feature: 

  • a grippy, textured vinyl pad that is slip-resistant, durable, and easy to clean. Note: Some pads come in the new CleanGrip® material.  
  • flat and incline options 
  • precise manufacturing with state-of-the-art robotics

The Nighthawk™ is the newest addition to our bench line up—and it is legit one of our best creations to date. This versatile adjustable bench features upgrades inspired by the earlier bestselling AB-4100 model. Constructed to be durable and compact, the bench provides unmatched stability and maneuverability through tactical weight distribution and a lightweight but rock-solid steel frame.

Other highlights for the The Nighthawk™:  

  • It has seven back positions and four seat positions for versatile training.
  • Constructed from 7- and 14-gauge steel, the frame is engineered to deliver exceptional durability and stability while maintaining a lightweight and compact design.
  • With a 16.7” height, this bench complies with International Powerlifting Federation standards.
  • Save space with upright storage.

If you want an affordable FID bench … 

Want to hit multiple angles – but you're on a budget? The AB-3000 2.0 is known as the best-value, adjustable, flat-incline-decline bench for home gyms. The back pad has eight adjustments, from 85 degrees upright to a -12 decline, and the seat pad also has five angle options. For decline, just swing the leg roller out from underneath the seat to secure your feet. No need to purchase an additional Leg Roller Attachment; it’s all built in. This is a classic, adjustable bench that gets the job done.  

Other highlights for the AB-3000 2.0 

  • Adjust the angle instantly and effortlessly by moving the bench into the desired ladder rung.  
  • The AB-3000 2.0 has updated CleanGrip® pads, which are denser and grippier than standard pads.
  • A horizontal handle makes it easy to move the bench around your gym.  
  • It’s solid, with heavy-duty bolts, 11-gauge steel, and a weight capacity of half a ton.

The AB-3100 bench

Try the AB-3100. This flat-incline bench is the most affordable and the lightest weight, while still featuring six back pad adjustments and three seat angle options. It has a lower weight capacity (700lbs) than most other benches and doesn’t offer a decline position — but it’s still incredibly sturdy. 

Other highlights for the AB-3100:   

  • The AB-3100 is made with 14- to 4-gauge steel frame and has grooved, rubber feet.  
  • The ladder-style design allows for easy and secure angle adjustment. 
  • Three legs instead of four leaves more space on the floor for your feet when bench pressing. 

If you hate the gap between the seat and back pad …  

The BlackWing Adjustable Bench
The BlackWing™ bench

No need to deal with the annoying gap between the seat and back pad on an adjustable bench. The BlackWing™ bench has  ZeroGap® technology, featuring a patented seat that slides forward and backward to eliminate the gap altogether. Out of the box, this hardcore bench allows for seven incline options. Or buy the optional Leg Roller Attachment to open up decline options, too.

If you want to customize your dream bench... 

The AB-5200 2.0

The AB-5200 2.0 is the toughest, most customizable bench out there. Choose a fixed post or adjustable post; the latter turns this bench into an FID bench. You can further personalize it by selecting a frame color, with the option to pick a different accent color on the guide rails. You can also choose a standard or wide pad right from the get-go.  

Other highlights for the AB-5200 2.0 

  • With an adjustable post, this bench has the most back pad angles.  
  • This bench meets IPF heigh standards.  
  • Store this bench vertically on its built-in, metal stand.  

If you want all the high-end features …

The BlackWing bench takes all the best features from all the best benches. It has it all. Decline options. CleanGrip® pads in wide or standard. An improved ZeroGap® technology feature. A closed ladder adjustment system. Compatibility with the Leg Roller Attachment for even more decline variations. Vertical storage. Even the seat pad is a unique combo of a ladder/pop-pin. Seriously, is there anything the BlackWing™ bench doesn’t have? (That’s rhetorical. This is the mother of them all.)  

More reasons to love the BlackWing™ bench:  

  • At 131lbs, this is the most robust bench, but it’s easy to move around thanks to its horizontal handle. 
  • This bench features tons of high-end details, like a laser-cut REP logo on the ladder and mountain logo on the front foot.  
  • A protective liner on the front foot keeps the bench in place and protects your floor.
