Product Description/Features
Assembled dimensions – 52 x 25 x 46.5 (in upright position)
Marcy’s adjustable bench will suit almost any weight lifter, including 6 different positions allowing for a wide range of exercises, we especially like this bench because of its combined user and weight load, at 600lbs
It is also one of the only weight benches in this price category to have an adjustable seat.

Design
Thankfully the Marcy adjustable weight bench has been designed with stability in mind, the wide back stabilizer bar does a great job of keeping the frame stable even when lifting heavy weights.
Marcy’s weight bench has a slight tapering back support, this will allow you more freedom of movement when doing exercises such as incline flys.
Bowflex’s 3.1 weight bench is the only other bench we would recommend for you that could rival the Marcy, check out our review here. With 15 yr warranty, you would expect the Bowflex to outclass the Marcy for quality and for the most part it does but only slightly.
The Marcy SB 670 has the adjustable seat, this is the biggest weakness in the Bowflex’s 3.1 armour and it will certainly sway many aspiring bodybuilders towards the Marcy.
Why’s an adjustable seat important? It helps stop your butt from slipping when incline bench pressing, in doing so it will help relieve the added stress on your lower back.

Marcy SB 670 Assembly
An easy to assemble bench, most people will get this bench up in under 30 mins, nothing too tricky, supplied with an allen wrench, you will need one extra tool such as a crescent wrench or socket for some parts.

Build quality
This bench is solid and stable, the bench does sit quite high but thanks to that wide back stabilizer, the height of the bench will not cause you any wobble issues.
From what I can see there’s only a 2 yr warranty on the Marcy. I was slightly disappointed, I’d expected at least a 10 year on the frame, Bowflex 3.1 has a 15yr on the fame so offering only a 2yr one might put some of you off.
I wouldn’t let the warranty put you off, this really is a top weight bench for the money, the powder coated 14 gauge steel frame should hold up to more than a few years of everyday use.
Adjustability
When it comes to adjustability, the Marcy SB 670 beats all of our other benches hands down, with six positions opposed to the Bowflex’s three and the only bench with the adjustable seat under $150. This bench sure does shine with versatility.

Exercises
Pros
Cons
No padded rollers for decline situps/presses? This might be a pro not a con for some
To Sum Up
An Impressive bench for the price, fully adjustable back support allows for a full range of upper body workouts. We’re certain you will not regret buying this bench with the adjustable seat and high quality 14 gauge steel frame this bench will be durable and solid. Bowflex’s 3.1 is the only other bench at this price point to challenge the Marcy SB-670
Great review of the Marcy Adjustable Weight Bench. We are in the market for one, as we quit our expensive training sessions at the gym. I figure it is time to do this on our own. I go to the gym for specific things. I don’t feel comfortable doing my weights or cardio there, I know…. So having something for home is perfect. This looks like a great solution!
Hi, The Marcy is a great choice for your first weight bench and offers as much versatility as most gym benches, you will be able to do a complete upper body workout with this bench…Make sure you buy a decent set of dumbbells to go with the bench, if you spend a little more they should last a lifetime.
This looks like a great option for the price! I guess the 2 year warranty isn’t too much of an issue as it is a reputable company that has been around a long time. Would you recommend this to someone who is just starting out? Is this entry price point? thanks
Great review.
It seems like Marcy did a good job on this bench. The price is acceptable and it has all features that you need to train your upper body. Except for the leg holders, but I also prefer a bench without leg holders. I had one with leg holders in the past and they truly were more an obstacle than a help.
I like the rear rollers because without them it can be annoying to carry the bench through the room if you want to store it. And you also have the danger to damage your floor without rollers.
I also like the adjustable seat. My bench had an adjustable seat as well and I was often times very grateful for this because it saved a lot of back pain that could have been caused by incline exercises.
Thanks to Marcy for creating such a flexible bench for such a good price!
Hi Sergej, I completely agree leg holders can be a pain, always check first before buying if the leg holders are detachable. Thanks for the comment.
Thanks for your comment Sergej, I agree you won’t find a more versatile, stable bench at this price.
