Bowflex SelectTech 5.1 Bench Review: Best for Dumbbell Training
The Bowflex 5.1 features a sliding seat pad that adjusts with the back angle, preventing hip-slipping on steep inclines — a detail most budget benches skip. Six positions flat to 90°, 480 lb capacity, folds upright for storage.
Capacity: 480 lbs | Positions: 6 (flat to 90°) | Seat: Adjustable sliding pad | Weight: 65 lbs
The natural partner for SelectTech dumbbells — engineered together for a reason. See all bench picks: Best Weight Benches for Home Gyms.

Who Should Buy the Bowflex SelectTech 5.1?
The Bowflex 5.1 is purpose-built for dumbbell training. If you own SelectTech adjustable dumbbells — or any adjustable dumbbell set — this bench was engineered to pair with them. The sliding seat pad moves automatically with the back angle, which keeps your hips in place during steep inclines instead of letting you slide forward the way a fixed seat does. That single design detail makes a meaningful difference when you’re pressing at 60° or 75°.
It’s a strong pick for home gym users who want a compact, quality incline bench without a massive footprint. At 65 lbs and with a vertical storage option that cuts the floor space to roughly 19″ × 11″, it fits comfortably in tight spaces. The 480 lb weight capacity is also well above what most home trainers will need, giving you room to grow.
The bench is 1 of 47.

Performance and Build Quality
In practice, the 5.1 feels solid. The frame doesn’t wobble or creak under load, and the adjustment mechanism between positions is firm — it doesn’t slip mid-set. The six back positions (flat through 90°) cover all standard pressing and curling angles, and the seat adjustments give you extra stability on decline-style movements.
The upholstery holds up well. The DuraFoam padding is dense enough for comfort across longer sessions without bottoming out. The surface has a slight grip texture that prevents you from sliding even at high incline angles — though the sliding seat pad does most of that work mechanically.
Assembly is straightforward and takes around 20–30 minutes with basic tools. The instruction manual is clear, and the bolt placements are labeled on the frame. Once built, the folding mechanism is smooth — one motion locks the bench upright and another brings it flat. This makes it practical to store between sessions without hassle, unlike some benches where the storage process is cumbersome enough that you end up just leaving them out.
For those who train at home and want to maximize bench versatility, the 5.1 pairs particularly well with the Bowflex SelectTech 552 and 1090 dumbbells. The dumbbell trays built into those models position the handles at exactly the right height for this bench when performing seated exercises. It’s a small usability detail, but it removes the awkward transition of picking up weights from the floor before every seated press set.
One honest limitation: the 5.1 is a dumbbell bench, not a barbell bench. There’s no rack attachment and the width isn’t suited for barbell work. If you’re splitting training between barbells and dumbbells, a utility bench like the REP AB-3000 or Flybird adjustable gives you more flexibility. But for pure dumbbell work — especially with high-range adjustable sets — the 5.1 is hard to beat at this price point.
What We Like
- Sliding seat pad prevents hip-slip on steep inclines
- Solid 480 lb capacity — well above average for a home bench
- Folds vertically for minimal storage footprint
- Six back positions cover every pressing angle
- Engineered to match SelectTech dumbbell dimensions
What Could Be Better
- Not suitable for barbell work (no rack, narrow width)
- Heavier than most folding benches at 65 lbs
- Higher price point than basic utility benches
How It Compares
| Bench | Positions | Capacity | Weight | Best For |
|---|---|---|---|---|
| Bowflex 5.1 | 6 (flat–90°) | 480 lbs | 65 lbs | Dumbbell training |
| REP AB-3000 | 7 + decline | 700 lbs | 85 lbs | Barbell + dumbbell |
| Flybird Adjustable | 7 | 620 lbs | 27 lbs | Space-saving |
| Marcy SB-228 | 5 | 300 lbs | 42 lbs | Budget barbell |
Our Verdict
The Bowflex SelectTech 5.1 earns its reputation as the best dumbbell-specific bench on the market. The sliding seat pad is a genuine ergonomic improvement over fixed-seat designs, the construction is durable, and the vertical storage solves the footprint problem that plagues most adjustable benches. If your training revolves around adjustable dumbbells, this bench is worth the premium. If you also train with barbells, consider a utility bench with a wider frame instead.
Rating: 4.5 / 5
How We Tested
We evaluated the Bowflex 5.1 over several weeks of dumbbell pressing, rowing, and curling sessions using SelectTech 552 and 1090 adjustable dumbbells. We assessed stability at each incline position under load, checked for wobble and seat movement during reps, and compared the sliding seat mechanism directly against fixed-seat benches at the same incline angles.
