Our Choice for Best Value Adjustable Sit Up Bench


XMark 12 Position Adjustable Decline Ab Bench

Since there are only so many ways you can angle an adjustable decline bench to promote a great ab workout we had to fall back on other things to select our best sit up bench.

The XMark was just more comfortable for us in every position and a small touch like the assist handle turned dismounting from a somewhat clumsy affair into a smooth, trouble free motion. Throw in the compact profile of the XMark, its ultra solid yet lightweight construction and its easy adjustability and you have our choice for best overall value in a decline/Ab bench.

Our runner up bench is the Fitness Reality X-Class Ab/Hyper Board which doubles as a hyper-extension unit, while also providing you with a tapered ab bench and 650 pound weight capacity. Rounding out our top 3 is the Finer Form Sit Up Board which is made from 14 gauge steel, has a 300 pound capacity and provides you with comfy 4-inch thick leg support rollers.
