Bowflex 5.1S Stowable Bench
Ranked #5 in Best Adjustable Weight Benches
Bowflex 5.1S Stowable Bench
$289.99as of Jun 7

The Bowflex 5.1S Stowable Bench is the pick for 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 lack of a flat-support post are the trade-offs 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
FLYBIRD Adjustable Bench
Higher ratedRanked #4 in Best Adjustable Weight Benches
FLYBIRD Adjustable Bench
$109.97as of Jun 7

The FLYBIRD Adjustable Bench is the entry-level recommendation for anyone spending as little as possible. Garage Gym Lab scores it 7.6/10 and names it their top budget pick, praising the price-to-feature ratio. It folds tiny, weighs under 30 lb, and offers true FID angles. The catch is a pad gap at steep inclines and a build that suits light-to-moderate dumbbell work rather than heavy barbell pressing.

Strengths
  • Shockingly low price, often around $110, for a folding FID bench
  • Folds to 14 x 14 x 32 in and weighs just 28.5 lb for easy storage
  • Seven back angles including a decline for genuine FID versatility
Watch-outs
  • Noticeable pad gap at steep incline angles, the main compromise
  • 800 lb stated capacity is optimistic for a 28 lb bench; treat it as light-duty
  • Only a 1-year frame and 30-day pad 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.

FLYBIRD Adjustable Bench

The cheapest bench here by far, undercutting the Bowflex 5.1S Stowable Bench by half and the REP Fitness AB-3000 FID by two-thirds. It can't match the stability of the REP Fitness AB-5200 2.0 or Rogue Adjustable Bench 3.0, but for light dumbbell training in a small space it punches above its price.
