The short version: for almost every first home gym, buy the FLYBIRD WB5. It’s the default budget flat-incline-decline bench, carries an ASTM-certified 800 lb rating that’s rare at this price, and adjusts from flat all the way to upright for pressing and rows. The FLYBIRD WB3is the better pick only if space is very tight and you know you’ll stay dumbbell-only — it’s the lightest, most compact bench FLYBIRD makes, but it has a lower capacity and is best kept away from heavy barbell work. Here’s the full head-to-head.
The quick verdict
Buy the WB5if you want one bench that does almost everything — flat, incline, and decline — with a certified capacity that comfortably handles barbell pressing. Buy the WB3if your space is genuinely small, you value a bench that’s feather-light to move and fold away, and you’re happy to keep your training to dumbbells. Both are solid FLYBIRD benches; the decision comes down to how tight your space is and whether a barbell is in your plans.
Meet the two benches
The FLYBIRD WB3is the lightest, most compact adjustable bench in FLYBIRD’s line. It offers adjustable back angles, folds down small, and is easy to pick up and move, which makes it a natural fit for apartments and shared rooms. Its niche is clear: enough positions for a proper dumbbell routine in a footprint that all but disappears when you fold it away.
The FLYBIRD WB5 is the default budget flat-incline-decline bench and the one most beginners should default to. It carries an ASTM-certified 800 lb rating, offers multiple back and seat angles, and adjusts flat to upright so you can press and row. It also folds flat for storage. It’s a larger, more capable bench than the WB3, built to be the single bench a home gym needs.
Capacity: the deciding difference
This is the row that settles most decisions. The WB5 is ASTM-certified to 800 lb, an independent standard that’s uncommon at this price and one of the strongest reasons to buy it. That certified headroom covers your body weight plus a loaded barbell with a wide safety margin, which is exactly what you want the moment you start pressing heavy. The WB3, by contrast, has a lower capacity than the WB5 and WB7.
The practical read: the WB3 is best kept to dumbbell work rather than heavy barbell pressing. That isn’t a knock — it’s simply what the bench is built for. If your plan is a dumbbell routine and nothing heavier, the WB3’s capacity is fine. If a barbell is anywhere in your future, the WB5’s certified 800 lb rating gives you room to grow without buying a second bench later.
Positions and versatility
Both benches adjust, but the WB5 does more. It offers multiple back and seat angles and goes from flat all the way to upright, so you can cover flat and incline pressing, decline work, seated shoulder work, and supported rows on one frame. That flat-incline-decline range is the backbone of a complete upper-body program, and it’s why the WB5 works as a true do-it-all bench.
The WB3 offers adjustable back angles— enough for a solid dumbbell routine, with the positions you need for incline and flat dumbbell pressing. It simply doesn’t reach as far or carry as much as the WB5. If versatility across barbell and dumbbell training matters to you, the WB5 is the clear winner; if you want a straightforward dumbbell bench that stores away, the WB3 has the angles you’ll actually use.
That versatility compounds over time. As your program grows to include overhead pressing, incline variations, and supported rows, having every angle on one frame means you’re never blocked by the bench — you reposition and keep training. It’s the difference between a bench that keeps up with a full program and one that quietly caps what you can do.
Storage and moving them around
Here the WB3 takes the round. It’s the lightest, most compactbench FLYBIRD makes, folds down small, and is genuinely easy to lift and reposition — ideal when your gym shares space with the rest of your life and has to disappear between sessions. If your top priority is a bench that tucks into a closet or slides under a bed, the WB3 is built for exactly that. Our apartment home gym guide leans on compact gear like this.
The WB5 also folds flatfor storage, so it’s far from a permanent fixture, but it’s a larger and heavier bench by design — that’s the trade for the higher capacity and wider range of positions. It stores neatly, just not as effortlessly as the WB3. For most rooms that’s a fair trade; for the very smallest spaces, the WB3’s portability can be the tiebreaker.
Comfort and extras
Neither bench is loaded with extras, and that keeps both affordable. The WB5’s pad is on the firmside rather than plush, and it doesn’t include a leg developer or other add-ons — it focuses its budget on the frame, the angles, and the certified capacity, which for a first bench is the right place to spend. A firm pad is actually an advantage under heavier pressing, where a soft surface can feel unstable.
It’s worth being realistic about what “firm” means in practice: over a long session you’ll notice the WB5’s pad more than a plush gym bench, but that same firmness is what keeps your shoulders planted when you’re pressing near your limit. Most owners settle into it within a few workouts, and for a bench meant to grow with you, stability under load is the more important trait. If a softer sit is a top priority, that’s a fair reason to look higher up the range — but it’s rarely a dealbreaker for a first bench.
The WB3 keeps things equally simple, prioritizing light weight and a small folded size over any frills. Neither bench is trying to be a plush, feature-packed station, and for a beginner that focus is a feature, not a shortcoming: you’re paying for a stable, adjustable surface rather than accessories you may never use.
Price and value
We won’t quote a number, since bench prices move — check the live price on our best adjustable weight benches page before you buy. What stays true is where the value sits: the WB5 is the budget do-it-all bench, and getting an ASTM 800 lb certification at its price is genuinely rare. That certified capacity plus the full flat-incline-decline range is a lot of bench for the money.
The WB3 competes on a different axis. Its value is in being the lightest, most compact option, so it’s the one to pay for when space — not versatility — is the constraint that matters most. For the majority of beginners who want one bench to grow into, the WB5 is the higher value buy; for the space-limited dumbbell-only lifter, the WB3 spends your money exactly where you need it.
Our pick: the WB5 for almost everyone
For almost every first home gym, buy the FLYBIRD WB5. It’s the do-it-all bench — flat, incline, and decline — with an ASTM-certified 800 lb rating that’s hard to find at this price, and it still folds flat when you’re done. That combination of capability and certified capacity means it won’t hold you back as you add a barbell and get stronger, so you buy one bench instead of upgrading in a year. That’s the high-value, low-regret path, and it’s the one we recommend by default.
When the WB3 is the smarter buy
Choose the FLYBIRD WB3when space is genuinely tight and you know you’ll stay dumbbell-only. If your bench has to fold away small after every session, live in a studio, or share a room, the WB3’s light weight and compact fold are worth prioritizing — and its adjustable back angles give you a real dumbbell routine. Just go in clear-eyed that it’s best kept to dumbbell work, not heavy barbell pressing. If you later find yourself wanting more bench than even the WB5 offers, our WB5 vs. WB7 comparison shows where the next step up pays off.
