REP FB-4000 Comp lite bench $115

 
The FB-4000 is one of the lowest-priced options in the bench department of REP fitness. This bench is a little beefier than the FB-5000 but not compatible with a Thompson fat pad. The full list of specifications is:
 
  • Total height: 17"
  • Total Pad Length: 45.25"
  • Pad Width: 12"
  • Total Footprint: 7 SQFT
  • Designed with Competition Standards
  • 3% Tolerance
 
If you want a good bench for a low price this is it.
 

Pros of the FB-4000 Comp lite bench

 
Pros of the FB 4000 bench are:
 
  • Light and easy to move
  • Low price
  • Single post design
  • Grippy cushion
 
The grippy cushion is one of the best product ideas of REP fitness for their benches. Combine it with a low price and single post design and you get yourself a good recipe for a nice bench for a home gym.
 

Cons of the FB-4000 Comp lite bench

 
The cons of the FB-4000 are:
 
  • Vertical handle
  • 700lbs limit
  • Finish
  • Instability when sitting on it
 
Vertical handles are not as good as horizontal ones for rolling your bench around. Minor issue, but still worth mentioning and will probably be fixed I future designs.
 
This bench has a 700-pound limit while others of REP fitness have a 1000 or even 1500 pound limit. If you want a big sturdy bench this is not the one. Even though you could bench 700 on this, I wouldn’t recommend it.
 
This bench is also designed for bench pressing, not for general use. The single post makes it unstable for exercises like hip thrusts or step-ups.
 

Alternatives to the FB-4000 Comp lite bench

 
 
The Rogue Utility bench and the TITAN hefty bench are good alternatives to the FB-400 if you want a thick pad or a multi-purpose bench.
 

Conclusion for the FB-4000 Comp lite bench

 
Good price , solid bench... can not do a lot wrong here.

REP AB-5100 Adjustable Bench $399

 
The REP AB-5100 bench is a good option with a push pin design that can also be turned into a decline bench. The only drawback of this design is that this is one of the benches with the widest gap between the two pads from REP fitness. The full specifications of this bench are:
 
  • 11-gauge steel frame.
  • 1,000 lb capacity.
  • Seven back pad adjustments & four-seat pad adjustments with laser-cut degree markings on a stainless steel wear guard.
  • Three large steel supports on the back pad and two on the seat pad for rock-solid stability.
  • Pivoting urethane grip handle and wheels for easy portability.
 
  • Total Height: 17.25"
  • Total Pad Length: 53.25"
  • Back Pad Width: 12.25"
  • Pad Gap: 3"
  • Overall Footprint: 7.5 SQFT
  • 3% Tolerance
 
This is a great bench to convert into a decline bench. Otherwise, you might want to opt for the REP AB 5200 or REP AB-5000 instead.
 

Pros of the REP  AB-5100 Adjustable Bench

 
The pros of the REP AB-5100 are:
 
  • Labeled degrees
  • Big and beefy
  • Heavy bench
  • Decline bench (attachment needed)
  • Pushpin safety
  • Wheelguards
 
The design is big sturdy and will meet the needs of big athletes who want to move big weights but do not have space for a dedicated be ch press station. The pushpin mechanism will provide further stability when benching.
 
The REP AB-5100 can also be turned into a decline bench. For this, you will need to purchase an additional attachment that comes in at slightly under $100. This is a nice upgrade option for anyone who wants to do everything with their bench.
 

Cons of the REP AB-5100 Adjustable Bench

 
The cons of the REP AB-5100 adjustable bench are:
 
  • Heavy bench
  • Hard to move
  • 90 degrees
  • Pushpin adjustments
  • 4-inch GAP
 
This bench is heavy and can be hard to move sometimes. While this is great when everybody is big and burly and might not be the best portable bench to get in a commercial setting with mainly average-sized humans.
 
The highest incline is an exact ninety degrees. I always find that to be quite uncomfortable for overhead presses as it easier to lean against a setup that still provides a 5-degree tilt in the highest setting.
 
The push pin adjustments can be hard to adjust. Compared with the fact that this bench is heavy this can get annoying. I am personally not a huge fan of the pushpin design on any bench as it does not allow for quick and easy adjustments.
 
The bench has probably the widest gap between the bottom and top pad compared to other be benches out of the REP fitness lineup. This allows for decline settings at the cost of a possible annoyance for flat benching. This is why o prefer the 5200 or 5000 models I am also not an advocate for decline benching.
 

Alternatives to the REP  AB-5100 Adjustable Bench

 
The alternatives to the REP AB-5100 bench are:
 
 
The REP AB-5200 is my personal favorite among the REP fitness benches. It is easy to adjust and move for a beefy bench and can be stored upright. The only drawback is the price.
 
The REP zero Gap bench is in a similar price range as the 5100 but provides the possibility the adjust the lower pad in a way that there is no gapping. If you really struggle on benches with gaps based on your build then this is the one to get. The downside is the pushpin mechanics. I always hated those and I just would not use benches that are being adjusted this way.
 

Conclusion for the REP-5100 Adjustable Bench

 
The REP 5100 adjustable bench is the best model from REP fitness if you are looking for a decline bench option. Otherwise, I would recommend the 5200 or 5000 models if you do not care about the decline.
