Exterior and Material: Crafted from a cast iron core and environmentally friendly TPU overcoat, these dumbbells are molded through high-temperature welding for a durable, resilient fit. The odorless, environmentally friendly, and wear-resistant TPU material provides both shock absorption and protection, effectively reducing noise and protecting floors. The black body with blue decorative patterns creates a professional and stylish look.

Structure and Durability: The integrated welding process provides a sturdy structure, eliminating the looseness associated with traditional detachable dumbbells. The polyurethane overcoat is impact- and abrasion-resistant, maintaining its integrity even with frequent training and drops, extending its lifespan.

Safe and Comfortable Design: The handles feature a non-slip electroplating process and a finely textured surface, ensuring a secure grip even with sweaty hands. They offer a comfortable and natural feel and resist slipping. The moderately ergonomic diameter reduces hand fatigue during extended training sessions.

Functionality and Training Effect: Suitable for a variety of exercises for the arms, shoulders, chest, back, core, and lower body. Whether it's strength training or full-body compound training, it can help improve muscle tone and beautiful lines.

Appearance: The round shape with blue decorative patterns exudes a modern and stylish feel. Unlike traditional black dumbbells, it is more suitable for those who value the texture and aesthetics of fitness equipment.
