Yaheetech Adjustable Dumbbells 18KG Adjustable Dumbbell Set 12 In 1 Adjustable Weights with Non-Slip Handle & Safety Locking Mechanism, Home Gym Strength Training Equipment for Full Bodybuilding

Double Lock Designs with More Safety: This dumbbell incorporates a two-step weight plate locking mechanism, which enhances overall stability, balance, and safety during exercise routines. The weight adjustment feature is activated only when the dumbbell is securely placed on the tray, preventing accidental operation during exercise

Space-saving & Safe Storage: Taking up only a small footprint of 40 cm L × 20.5 cm W × 20.5 cm H, this adjustable weight saves significant space compared to other 12 standard sets. Easily stow it beneath a workout bench or on a garage shelf post-workout

Anti-slip Handle for Intensive Workouts: Tailored for comfort and control, this strength training dumbbell boasts a 3.7 cm diameter handle with anti-slip convex textures. The blend of hard and soft materials (PPR & ABS) elevates grip strength and ensures comfort during rigorous workouts

Secure & Silent Dumbbell: This hand weight includes a robust dumbbell base to prevent any movement or tipping when storing the weight places. Plates stay securely in place during workouts, minimizing noise and ensuring stability

About Weight Adjustment: To adjust the dumbbell weight, fully insert the handle into the base (in the lowest position) before turning it. Align the red arrows with the numbers on both dials until you hear a "click-clack" sound, confirming the adjustment. If the red arrows aren't aligned, please reset the handle and adjust it again
