Twist arm trainer

A twist arm trainer is a compact fitness device designed to strengthen and tone the muscles in the arms, shoulders, chest, and upper back through rotational resistance. It typically features a durable, spring-loaded or resistance-based mechanism that requires users to twist or rotate the handles inward and outward, engaging multiple muscle groups simultaneously. This makes it an effective tool for improving upper body strength, enhancing muscle endurance, and promoting joint flexibility. Lightweight and portable, the twist arm trainer is ideal for home workouts, office use, or travel, offering a convenient way to stay fit and build muscle without the need for bulky gym equipment.
