PowerLine PAB21X Ab Bench Review

PowerLine PAB21XRecently I’ve reviewed a lot of power racks, so this time I took the liberty to review something different. Since summer is already on us, a lot of people started wondering how to improve their abdominal muscles. After a little bit of research, you will find out that it’s not just crunches. There are actually machines specifically designed for multiple ABS exercises. So let’s take a closer look at one such machine – PowerLine PAB21X Ab Bench.

PowerLine brand is well known in the fitness industry, they make a lot of fitness equipment.  I’ve already reviewed one of their power racks and now we will take a look at one of their Ab benches. So what can you expect from PowerLine PAB21X?

Features of PowerLine PAB21X Ab Bench

  • Designed to provide a range of motion abdominal resistance exercises
  • Curved back pad to provide the maximum-intense abdominal contraction
  • Sturdy 3” x 4” inches four-side welded frame
  • Supports Olympic Weight plates
  • Ball-bearing pulley designed to provide complete movement freedom for each core muscle group
  • 10-year frame warranty

People are often sceptical when it comes to ab machines, simply because we have crunches, right? But I can assure that full spectrum of abdominal muscles cannot be trained with just crunches.

Package & Assembly

PAB21X arrived in one box, which weighted around 46 lbs with dimensions of 37 x 18 x 37 inches. The machine was tightly packed, nothing was wondering around the box.

The assembly was very easy and it took me less than 30 minutes. If you are a small person you might need the second set of extra hands though, so it would be best if you had some friend helping you out. One downside was that the bolts were not marked properly. The only part where you need to be extra careful is with the pulley, so it won’t get cut or twisted. Well that was basically it.

Play Time!

First of all, the frame itself is not heavy and it looks like it’s gonna tip over every minute, but it’s quite sturdy, even for a larger man.

After trying it I was surprised that despite the fact that the back pad is looking very firm, it is actually very comfortable on the back. It is, of course, adjustable and slides smoothly up and down after you ease the thumbscrew. The one thing that immediately came to my attention was the back pad’s size, though. I’m 5’10 and while I was comfortable, a taller person might experience issues when trying to sit properly. Another thing that caught my attention was the sitting gap. It takes time to get comfy there.

I decided to try out the pulley and was quite surprised how strong it was and how smoothly it rolls, so no extra grease is needed to be applied. I’ve used 80 lbs total weight, made of 20 lbs standard plates and there wasn’t any problem. The back of your head is fully supported by straps when exercising. Straps themselves are very sturdy as well.

Pros & Cons

As with every item, even PowerLine PAB21X has some pros, but some cons as well, so let’s get right to it.


  • Sturdy Frame and Straps
  • Comfortable & Firm Back Pad
  • Strong Pulley with Smooth Rolling
  • Long Frame Warranty (10 years)
  • Great Price


  • Back Pad is Not Very Long (6’2 + People Might Not Sit Comfortably)
  • Sturdy, but Very Light Frame
  • Sitting Gap Might Not Be Comfortable for Larger People
Final RecommendationRating
In short, this is one good piece of equipment to get if you are up for some great abdominal core exercises. The PowerLine PAB21X is one small, sturdy & mostly comfy ab bench. While I would not recommend it to very tall people (6’2+), I would totally recommend it in general.
