Resistance bands are valuable tools in strength training due to their ability to provide progressive resistance throughout movements. Unlike traditional weights, bands can be adjusted to accommodate different fitness levels and are versatile for targeting various muscle groups. They help improve strength, stability, and range of motion, making workouts effective and safe. Additionally, resistance bands are portable and can be used in various settings, allowing for flexibility in training routines. They also encourage proper form, minimizing the risk of injury during exercises.
