.There’s not much I can say this bench doesn’t feature. With an adjustable seat, 6 adjustable back support positions this bench is by far the most versatile of all the weight benches in this price bracket.It’s made from high-quality powder coated steel and will prove to be a durable weight bench. Well made quality 2 toned upholstery with high-density foam, gives this bench the right amount of comfort and padding, it’s a nice looking bench too.A wide rear stabilizer bar makes sure the SB 670 does not move around while you are pressing heavy weights. The Marcy adjustable bench will appeal to the beginner through to the more seasoned lifter, with a maximum weight load of 600lbs, it’s sure to last a while before you grow out of it.Our only adjustable bench with an adjustable seat, an important feature most serious weight trainers will not go without and great to see in the under $150 bracket. It will stop your butt sliding when pressing in the lower incline positions.No leg holder for decline training but to be honest, decline bench pressing is overrated, I’d recommend you do some weighted dips for this, you’ll add mass quicker, and if you are wanting to do some decline situps you should be able to hook your feet under the seat.It’s hard to separate the top two benches. The 3.1 has the awesome build quality vs the versatility of the Marcy, Bowflex has the reputation for making some of the best-engineered home gym equipment out there and with a 15-year guarantee I like their confidence.Marcy offers a 2 year frame warranty but the build quality is great and it has the adjustable seat, that I personally wouldn’t go without, this is the main selling point of the Marcy for me, and don’t forget the user and weight load. The Marcy promises 120lbs more than the Bowflex, so depending on how you are training and how quickly you will be adding muscle and increasing the weight load, the Marcy may be the best option if you are thinking of lifting heavy in the future.A solid, stable good looking weight bench the Marcy offers you the user a great deal of versatility for the price, compatible with many smith machines and racks, it’s certainly the 3.1’s closest rival.
