FED Fitness Flybird WB6 Review for Quick At‑Home HIIT Circuits in 2026

For fast, intense at-home HIIT circuits, a bench can’t be bulky, wobbly, or annoying to set up between intervals. The FED Fitness Flybird WB6 Foldable Adjustable Weight Bench Classic aims squarely at that problem: it’s almost fully pre-assembled, folds to a footprint small enough to slide under a sofa, and offers enough adjustability to cover everything from decline core work to upright presses.

Because no competitor data is available beyond an error message, this review focuses on what we can verify about the Flybird WB6 itself and how it fits into a home HIIT setup in 2026.

Based on the product information, the Flybird WB6 (now sold under FED Fitness) is built as a compact, adjustable, and relatively heavy-duty home bench:

• Nearly no assembly: It arrives 96% pre-assembled, with just one final step before use. That matters for anyone who doesn’t want to spend an evening with tools before their first workout.
• Multi-angle adjustability:
  - Backrest: 8 positions from –30° (decline) to 90° (upright)
  - Seat: multiple incline positions
  A spring-loaded quick pop-pin makes angle changes fast and secure—helpful when you’re changing positions during timed HIIT intervals.
• Foldable & compact storage:
  - Folded footprint: 0.91 sq. ft.
  - Folded thickness: 9.5"
  - Stowed dimensions: 30.1" x 13.8" x 9.5"
  It’s designed to fit under most beds or sofas, which is ideal if your “gym” is also your living room.
• Build quality & stability:
  - 1.4 mm thickened steel frame
  - Triangular support structure
  - Wide, square feet with leveling feet for stability on slightly uneven floors
  This combination is meant to reduce wobble—critical for safe step-ups, presses, and rows during fast-paced circuits.
• Comfort & ergonomics:
  - 30" extended backrest to support more of your torso
  - Grippy Woven-Tex leather to keep you from sliding during decline or incline moves
  - 2.4" high-density padding for comfort without feeling squishy or unstable
  FED Fitness also provides detailed backrest and seat dimensions and gap info, which suggests they expect buyers to care about fit and setup tolerances.

For a 2026 home HIIT routine that cycles between dumbbell presses, rows, Bulgarian split squats, core work, and step-ups, the Flybird WB6’s spec sheet lines up well with real-world needs.

Stability and Capacity

• Max weight capacity: 880 lb (400 kg)
  This is unusually high for a home bench, at least on paper. For HIIT, the “weight” is a combination of your body plus any dumbbells or kettlebells you’re using; 880 lb of rated capacity offers a significant margin of safety.
• The triangular structure and wide feet should help keep the bench planted during lateral movements or dynamic transitions, which is especially important for moves like:
  • Bench jump-overs
  • Elevated push-ups and planks
  • Bulgarian split squats
  • Renegade rows where any wobble can kill your pace or confidence

At 30.1 lb item weight, the bench is light enough to move between exercises but not so light that it feels flimsy.

Adjustability for HIIT Variety

For HIIT, versatility matters more than niche bodybuilding angles. The WB6’s –30° to 90° range covers:

• Flat and decline core work: decline sit-ups, Russian twists with feet anchored, reverse crunch setups.
• Flat and incline presses/rows: quick angle changes mean you can alternate between flat dumbbell presses and incline presses in the same circuit without losing much time.
• Upright position (around 90°): seated shoulder presses or supported curls when you want to push intensity without loading the lower back.

The spring-loaded pop pin is especially relevant for circuits: instead of unscrewing knobs or wrestling with stiff hinges, you can quickly click between angles during a 15–30 second rest window.

Space and Setup in Small Homes

The bench’s 0.91 sq. ft. folded footprint and 9.5" thickness make it practical for small apartments or multipurpose rooms. In a real HIIT scenario, you can:

1. Pull it out from under a bed or sofa.
2. Unfold it and lock the pin.
3. Run through a 20–30 minute session.
4. Fold and stash it away again.

The 96% pre-assembly also means you’re not delaying your training start by days or hours—particularly helpful if you’re buying the bench as part of a New Year’s 2026 fitness reset.

Comfort and Feel

High-density 2.4" padding and grippy Woven-Tex leather matter more than you might expect in HIIT:

• The denser foam helps you feel stable under heavy dumbbells during intervals—less energy lost to wobble.
• The grippy surface helps prevent sliding on incline or decline moves, especially if you sweat mid-workout.

For repeated daily use, this combination is more forgiving on shoulders, hips, and upper back than thinner, firmer utility benches.

Warranty and Support

For a bench that may see daily or near-daily use in 2026:

• 1-year warranty plus lifetime technical support
• 30-day money-back guarantee
• Free shipping (3–7 business days)

That’s enough coverage to feel reasonably comfortable if you’re buying online without trying the bench first, and it suits the mid-priced nature of the product.

According to the provided data, COMPETITOR_INFO could not be loaded due to a timeout error, and no specific competing models, brands, or URLs are available. Because of that, we cannot name or accurately contrast this bench with specific competitors.

What we can say, based solely on the Flybird WB6’s verified information, is how it positions itself in the broader category:

• Versus typical budget flat benches:
  The WB6 clearly offers more angle adjustability, far better folding and storage, and a much higher stated capacity than basic flat benches that often dominate the cheapest tier of home equipment.
• Versus many adjustable benches without folding:
  Its ability to fold under 10" thick and occupy under 1 sq. ft. of floor space stands out for apartment dwellers and anyone using a shared living room.
• Versus premium gym-style benches:
  Heavy commercial benches may still offer more rock-solid stability, full commercial warranties, and sometimes higher true capacity. But they’re usually much heavier, non-folding, and aimed more at permanent home gyms than quick HIIT-friendly setups.

Because we have no concrete competitor models, URLs, or pricing for direct head-to-head comparisons, we cannot provide a ranked list or a multi-product comparison table without inventing information. Within those limits, the WB6 appears to be a strong, space-saving adjustable bench option for people building quick at-home HIIT circuits around dumbbells and bodyweight work.

The FED Fitness Flybird WB6 Foldable Adjustable Weight Bench Classic is well-suited to quick, high-intensity at-home training in 2026 if you:

• Need a foldable bench that can disappear under furniture.
• Want fast angle changes for multi-exercise HIIT circuits.
• Care about stability and high weight capacity for heavy dumbbell intervals.
• Prefer minimal assembly and straightforward setup.

It may not replace a heavy commercial bench in a dedicated powerlifting space, but for most people building a compact home HIIT station, the combination of strong specs, easy storage, and adjustability makes it a convincing choice—especially at its promotional pricing.

If you’re planning a new routine, pair it with adjustable dumbbells or a training bar and build a handful of 20–30 minute HIIT circuits that you can run several times a week. Before purchasing, it’s still smart to compare current prices and user feedback, but on paper, the WB6 checks the key boxes for convenience-focused home workouts.
