Pros & Cons

What we like ...
  • Meets IPF standards for weight benches (on an adjustable bench. Not typical!)
  • Same number of adjustments as the REP AB-5200
  • Sells for just under $400, a great price for a quality weight bench
  • Seven different color options
What needs improvement ...
  • Back pad is a little shorter than the AB-5200
  • Doesn’t have a decline option
  • Nit-picky here, but the knobs feel unnecessarily cheap

Product Summary

The REP AB-4100 is one of the best adjustable weight benches on the market today. Not only does it have a minimal pad gap, at 1.57 inches, but it also meets International Powerlifting Federation (IPF) standards for weight benches and is lightweight at only 85 pounds.

One of the only drawbacks of this weight bench is the lack of a decline option, but that probably won’t be an issue to most home gym owners. What you do get is a heavy-duty piece of equipment at an affordable price point.
