Ranked #4 in Best Adjustable Weight Benches

Bowflex 5.1S Stowable Bench

4.2

3 sources2 derived$329as of Aug 1

The Bowflex 5.1S Stowable Bench suits space-limited dumbbell trainers. It folds flat and parks against a wall, weighs only 60 lb, and offers six angles down to a -20 degree decline. Garage Gym Reviews rates it 3.8/5 and notes it is suitable for non-competitive lifters rather than powerlifters. The 600 lb capacity and missing flat-support post are what you trade for the storability.

Strengths

— Folds and stows vertically against a wall, ideal for tight spaces
— Six positions including a -20 degree decline for ab and dumbbell work
— Adjustable seat pad keeps you from sliding on inclines

Watch-outs

— 600 lb capacity is well below the 1,000 lb benches at a similar weight rating
— Garage Gym Reviews scored it 3.8/5, citing limited support for heavy lifters
— No flat-bench head support post; not built for max-effort barbell pressing

REP Fitness AB-3000 FID

4.6

3 sourcesall derived$349.99as of Aug 1

The REP Fitness AB-3000 2.0 FID is the value champion of adjustable benches. Roughly $320 buys an 11-gauge frame, a 1,000 lb capacity, eight back angles, and genuine decline functionality. BarBend calls it a great deal at the price, and Garage Gym Reviews calls it probably the best adjustable bench for the money. It gives up a little refinement to the AB-5200 and costs hundreds less.

Strengths

— Best-value FID bench by a wide margin, around $320 with full decline capability
— 1,000 lb capacity on an 11-gauge steel frame at a budget price
— 8 back-pad angles and 5 seat angles cover flat, incline, and decline work

Watch-outs

— Two-post design leaves a slightly larger head-end pad gap than the AB-5200
— Pop-pin adjustment is fiddlier than the AB-5200's ladder system
— Pins carry only a 1-year warranty

How they stack up

Bowflex 5.1S Stowable Bench

Lighter and far cheaper than the REP Fitness AB-5200 2.0 and Rogue Adjustable Bench 3.0, but its 600 lb capacity trails the 1,000 lb REP Fitness AB-3000 FID. Pick it over the FLYBIRD Adjustable Bench if you want a known brand, a seat decline, and the longest frame warranty in this group.

REP Fitness AB-3000 FID

The smart-money alternative to the REP Fitness AB-5200 2.0: same brand, same 1,000 lb rating, hundreds cheaper, with a slightly bigger pad gap. Far more bench than the Bowflex 5.1S Stowable Bench or FLYBIRD Adjustable Bench, and it undercuts the Rogue Adjustable Bench 3.0 by roughly half.
