Keppi Adjustable Dumbbell Set — 25 lb / 40 lb / 55 lb / 60 lb Options, Fast-Adjust Metal Handle with Anti-Slip Grip for Full-Body Workouts

- 5-in-1 Compact Design: Each dumbbell measures 15.9" × 9.4" × 10.4", so the pair can substitute five fixed weights (typically 4 lb, 13 lb, 22 lb, 31 lb, 40 lb per hand) and frees up space in apartments, home offices, or small gyms. - Rapid One-Hand Adjustment: Twist-style handle enables instant single-hand changes from 4 lb up to 40 lb in about one second for seamless exercise transitions and faster training pace. - Dual Safety Locking: A base release combined with a dialing mechanism that includes eight safety slots locks each steel plate securely, delivering stable, rattle-free performance during dynamic movements. - Ergonomic Non-Slip Handle: Specially textured, sweat-resistant grip with an ergonomic profile provides superior hold, reduces hand fatigue, and maintains control through intense sessions. - High-Grade Steel Plates: Precision-cut premium steel weight plates offer outstanding strength and long-lasting durability to withstand regular home or gym use. - Broad Weight Progression for Programmed Training: 4–40 lb settings support light warm-ups and isolation moves (raises, flyes, curls, triceps extensions), mid-range compound exercises (presses, rows, lunges), and heavier strength lifts (deadlifts, bench press, overhead press, squats) for progression from beginner toning to intermediate muscle building.
