AB-3100 Adjustable Weight Bench

AB-3100 Adjustable Weight Bench

The AB-3100 is REP’s most affordable adjustable bench, while still featuring six back pad adjustments (from flat to 90 degrees) and three seat angle options (from flat to 20 degrees). The AB-3100 is a heavy-duty, flat-incline bench (no decline position) with a three-post design, so the legs of the bench won’t get in the way of your feet while pressing. Easily and securely switch angles with the ladder adjustment design. For extra stability, the AB-3100 features grooved, rubber, grippy feet on all three contact points, plus a vertical tube for added support under heavy loads (weight capacity: 700lbs). The pads are covered with a non-slip, textured vinyl that holds lifters in position and is easy to clean. The seat pad slightly tapers for comfort, with a small 1.75” gap between the back and seat pads. The AB-3100 comes in four colors: metallic black, red, blue, and matte black.

Have had two of these benches in the gym for 6 years. They have held up well to daily use. Incline options are all solid. Does have a little play at times but overall a great option for an adjustable bench at a good price.

Great value bench. Can easily be used as your only bench in the gym though I do supplement mine with a flat bench with a wide pad. It can feel a little wobbly but as soon as you handle some weight in your hands with a barbell or dumbbell it feels more locked down. I wish there was a more comfortable upright seated angle. The steepest is 90° and its almost too upright for barbell work but then the next increment down (75° I believe) feels too much like a high incline. Still a great bench overall.
