REP AB-4100 Adjustable Bench Review: Sneaky Value!

✅ REP AB-4100: www.garagegymreviews.com/go/r...
Lightweight, highly adjustable, and durable are just some of the words to describe the REP Fitness AB-4100 adjustable weight bench. Seriously, this thing is capable of doing almost anything.
Along with having a minimal gap (only 1.57 inches) and a 12-inch back pad, the AB-4100 comes with a ladder-style adjustment mechanism so you can pick from 7 back position and 3 seat positions. For extra security, the bench comes with a closed ladder design so you can lift with full peace of mind.
Oh, did we also mention 7 different color options?

Just ordered this Friday and the main reason I went with it over the 5200 was the weight. Home gym is shared with my wife and want things she can also handle and get into the position she wants.

[@hitleractually8180]

The only positions she should concern herself with is being on all fours or standing up right in front of the stove.

[@jaysav8958]

I made the mistake of getting the 5200 without paying attention the weight. I ended up selling it and will be buying this

[@LakeLake123]

Got one a couple weeks ago. Very impressed with the quality and design! Highly recommended. Can’t imagine ever needing anything more heavy duty than this.

[@zedl]

how are you liking it after 9 months of use?

[@painfreemovements]

Wow!!! You didn't use fillers on this video!!! Amazing improvement in few weeks Coop!! You save me money by doing great reviews to help me choose the right equipments on my first try!

[@joecowan3719]

Coop in his home gym, reviewing the new releases, classic GGR, LOVE IT!

[@JoseLuis-ph4iz]

I am so glad this video popped up. I was about to pull the trigger on an AB-5200 but fortunately they are out of stock. This AB-4100 is definitely a better option for me. Thanks Coop!

[@davidcooper2516]

On the basis of this review, I purchased and just received my 4100 REP bench, and after assembling and using it, I couldn't be more impressed. This piece of kit is a monster, in the best sense. Easy to assemble and adjust, masterfully designed, a pleasure to use, and robust in construction, well beyond any conceivable weight requirements I'll ever have. Your comprehensive reviews are much appreciated, and have led to several valuable acquisitions for my home gym. Very glad I found your channel.

[@marshallliu8529]

Decided to go with the 4100 after seeing this video. Previously completely disregarded it due to raves about the 5200. Seems to have all the value without any sacrifice in any of the major features. Thanks for the informed video!

[@Ahkomaton]

I bought this bench 2 days ago and this review helps justify the decision. Thanks coop!!

[@davidpneuman3940]

Picked this bench up a few weeks ago and really like it so far. Originally bought the AB-3000 and exchanged it when the 4100 came out like a week later. Very easy to maneuver, feels solid, looks great, and I can stand it up to free up more space when necessary. Glad I exchanged the 3000 for this. Got the white as well.

[@cameronpoulton9490]

@@googleaccountname6768 thanks for the service man. What’s wrong with the decline option on the bench though? Is it just too extreme of a decline?

[@richards6431]

Have a small lightweight bench in a garage gym is a great idea. I have a beast of bench and it is a pain in the ass to move. It is also great having a ladder design. Mine is a pop pin, also a pain. Great review.

[@finkfamily7116]

Great review Coop. I think I just found my future bench. Thanks

[@preston0808]

Hey Coop, I see those delts popping. I have a similar body type to you, and I know you've worked hard for those gains. Nice work

[@DampRaccoon]

You mentioned a couple of times that most garage/home gym owners are using dedicated flat benches in addition to an adjustable bench. I'm not sure that's true.

[@rquattro11]

I completely agree with you. What's the point in having 2 unless u compete in powerlifting?

[@GarageGymReviews]

This is a great point that I’d actually like data on. I was just guessing, but very well could be off. I’m going to run a poll and then we can all know. Appreciate the call-out because my assumption could very well be off. - Coop

[@bryanmiranda1061]

@@GarageGymReviews Space saving is absolutely crucial for me in my garage gym. I prefer to only have one versatile bench.

[@DampRaccoon]

@@GarageGymReviews Data would be great. For most that have two benches, it would also be nice to know why. Unless excess space/money, many might have ended up with two not by choice, but by gym build out evolution (e.g. starting with one bench thinking that just a flat or incline would satisfy their needs, but later finding they wanted incline back or that a cheaper adjustable/gap/etc. wasn't preferred for benching. So, knowing if one or two is preferred might be a separate question than what people have. Might place a different perspective on some review aspects but other than that, keep up the great work.

[@joecowan3719]

@@DampRaccoon I am sure my wife and I may be the exception and not the rule, but we hsve 3 set up as different stations in our modest 600sqft basement gym. One lives in the rack, one is a db station and one is leg station. For some of us that have multiple people training at the same time and like having stations ready to go for super sets or time consuming to set up and break down exercises, multiple benches can be very valuable. Setting up your gym with the equipment you need in a manner that fits what is most important to you. For many cost is most important, for some others it is efficiency of time IMO.

[@craterflakes]

Great review, awesome bench, and always love seeing Assambly Sam!

[@Will-T.]

Mine just shipped! I took a gamble buying it before Coop put out a video on it. Glad to hear it seems it'll pay off since Coop likes it so much!

[@jwm2762]

asSAMbly is the best pun / actually useful input of any product review - gotta keep em going

[@GarageGymReviews]

Agreed. Assambly is such a big part of some of this equipment so I think it's helpful for gym owners.

[@JimmyBeans84]

How timely. I was going back and forth between the 4100 and 5200. This helped seal the deal for me. Unrelated, but it would be the bee's knees if you eventually get around to reviewing the Bells of Steel Belt Squat vs. the Titan Belt Squat V2. Your review only covers the V1, so I think plenty people would be interested to see your thoughts on the updated version since it is the most economical belt squat outside of DIY nonsense.

[@bucobrews9513]

solid review as always. I really like this bench. Id like to see how it compares to the FIDAB-2 adjustable bench. Also if you want to do a decline you can just throw a 35 lb plate under the front foot since that's all they are good for. lol

[@tonya7699]

Looks like an awesome bench. I have a few REP products and I've been really happy with them.

[@BasementBrandon]

I actually like a heftier bench, luckily I’m so jacked they all feel light.

[@chainrxn159]

jacking... what, exactly?

[@GarageGymReviews]

During use, I just feel no difference in the stability of a bench between my Sorinex NP-3 Benches and my Prime Bench and they're in different leagues in terms of weight.

[@Fartking_69]

I come here for this

[@BasementBrandon]

@@GarageGymReviews Hmm, I've found that lighter benches feel less stable when in the incline position. Maybe I'll have to pick one of these up to test it.

[@BrandonSchwartz1]

We all know those KZbin videos of you prepping for the powerlifting meet are heavily edited and use custom fake StrengthCo plates. The secret’s out man

Should have gotten purple or green... No one else stocks those colors white is a little different... Thanks for the video

[@davidwoods7221]

I bought the 5200 a while back and I was in the market for a smaller/easier to move bench so the big heavy 5200 could live in the rack. REP came out with this 4100 and I bought like 2 days later. I love it! It's so easy to move around and feels just as stable as the 5200. Also the purple powdercoat isn't textured like that and it looks REALLY high quality.

[@andrewwebster15]

Love the concise aSambly

[@mach5jeep]

Rep could easily sell the serrated adjustment rails that encapsulate the adjuster and a tail piece so you can stand up a 3100 as an upgrade to those who already own a 3100

[@TheSasquatchNation]

I think you sold me on getting this bench.

[@johne7212]

Coop, Really appreciate your videos. Have learned so much from your channel! Looked like you referenced a 3D-printed piece to allow you to stand up your Prime Fitness adjustable bench. I actually bought that bench based on your recommendation. Where can I get that 3D printed piece???? Thanks!

[@BobJob42]

Coop, great review. How do you think this compares to REP's AB-3000? the 3000 offers the decline option

[@GarageGymReviews]

Working on a review for the rest of their benches, especially the more budget friendly ones.

[@williamallen5369]

I do think ironmaster should go back to old pricing to be more competitive, their recent price increase has been quite a large jump. I would agree with you due to the price differences, as long as you didn't need a decline feature or want attachments, that the Rep AB4100 is a better buy than the IM super bench.

[@plmn93]

Ironmaster can't keep benches in stock, so I wouldn't expect a price cut anytime soon.

[@bcarter9252]

Need another adjustable bench as the dog works out (sleeps) on my AB-3000

[@ericdunthorne1981]

So would the AB-5000 be the best bench if you want the decline option?

[@julie.c7199]

Great helpful review!!! I am watching one bench from JOROTO fitness, the model is JOROTO MD80, will you have a plan to review this bench?

[@twistedbarbell3950]

Totally agree about the excess weight of the 5200. I love it, but I always have to be mindful of my mechanics when lifting and moving it around, just to be safe. I wish it were easier!

[@squealer42]

Flybird makes a sweet Full-body adjustable ironing board ☺

[@raymondtedstrom6739]

I have been outfitting my home gym and ordered a 4100 instead of a 5200, largely because of the weight difference for my wife's sake (see that other youtube guy's wife's complaints of the 5200). So yes, it absolutely cannibalizes 5200 sales.

[@amunra4256]

For what it's worth, my wife is 5'2" and almost never works out, and she can move my 5200 with general ease. But the 4100 does look like a fantastic bench as well, and $100 cheaper is very nice. Highly doubt you'll regret that purchase

[@midcityscott]

I’d like to see more reviews of tru grit and bells of steel as a whole.

[@connormckay9429]

I just wish you could add Leg rollers to this so you could do normal sit ups on it. Might wind up going with the 3100 for that reason but this also has a lot of features I like over that one too

[@13tcc]

Would this fit a 6.0’ person? Btw, love your reviews 👍

[@renodeify]

I just received my AB-4100. With all the positive reviews and recommendations online, I have to say I'm very disappointed. I didn't expect it to be as good as the commercial grade benches that they have at my gym but wow this thing wobbles. A lot. The ladder mechanism also makes noise as the bench wobbles when it's set to flat because of the double support design. I tried tightening the bolts as some have suggested online but it didn't help much at all. The problem is the frame itself is not stiff enough and it twists way too much. There are also some defects with the powder coat and stitch work. The only positive that I can say about this bench is it has the right height and the padding is nice. This will be the last REP product for me.

[@Pr0noTrigger]

I was waiting for this video, so thank you! But I’d be pissed if you convinced me last video to get the ab-5200 only to say this one is good enough lol. 4100 it is!

[@hitleractually8180]

It's a $100 dollar difference. $100 is nothing! You probably spend that a month at Starbucks. For an expensive hobby, home gymers are some of most ridiculous, frugal, penny pinching misers I've ever seen. Nobody got into this hobby to save money. This is one of the most expensive interests you could take up.

[@plmn93]

@@hitleractually8180 I almost agree. A lot of this equipment will last decades if not a lifetime so why scrimp? But I have saved money with my home gym. My rack is going on 20 years old and the entire family uses it. I have less invested in my gym than what a gym membership would have cost over 20 years for me alone. But in this case it's not really about the money. The 4100 is still a quality bench that will be nicer to use on a daily basis for most people. Heavy benches are annoying, and women and kids often can't deal with them at all. That's why I still have my old PowerBlock bench. It's not the greatest, but it's easy for everybody to use.

I think when the cushion gets softer near the hinge that might poke you enough to make you readjust.

[@kennethsollenberger7937]

The powder coat on the purple one had no texture on it. Nice and smooth. Maybe the white comes with the hammered texture.

[@bren_miller]

Would recommend Irwin Fitness Supply’s AB 1.0 out of Manitoba, Canada. Not only do they make badass products, it may be beneficial for Americans to order Canadian products with the exchange rate. It’s on par with the Rogue AB 3.0 in price and is aesthetically more pleasing.

[@beaubjarnason4759]

Shhhhhhh you’re not supposed to talk about Irwin. Now they’ll sell out. Just found their gear the other day. Wow, it’s impressive. Can’t wait to see some in person.

[@BigBackInk]

I think Sam kind of complaining about the screw in foot pads is kind of knit picking. I don't think those are going to loosen that much, for the most part its going to be on the ground and it's not going to take much to screw them back down... Also you could just put some Lok-tight on the threads and call it a day.

[@apeekintime]

I would wager they plan to increase the price on their AB-5200. Due to inflation, material cost, and shipping they are not keeping the margin they want per unit. Putting out a middle tier option will let them reposition the 5200 as a luxury/commercial grade piece.
