A weighted vest is a type of clothing designed to add extra weight to the body during physical activities. Typically made from durable materials, these vests contain pockets that can be filled with weights, allowing users to customize the load according to their fitness level. They are commonly used in exercises like running, walking, or strength training to enhance resistance and improve overall workout effectiveness. Using a weighted vest can help increase muscle strength and endurance by making workouts more challenging. It can also boost calorie burn, making it a popular choice for athletes and fitness enthusiasts. However, it's important to use them correctly to avoid injury and ensure proper form during exercises.
