The rubber band is 110 cm long. When lightly stretched, it extends to 170 cm, and when strongly stretched, it reaches nearly 200 cm. A must-have for all fielders, not just pitchers. Daily strengthening and maintenance are ideal to prevent elbow or shoulder pain from ruining your baseball time with a doctor's order. Perfect for practicing throwing mechanics, including elbow, shoulder, lower body, core, muscle strength, finger usage, and follow-through, instead of catch. It's also ideal for practicing the body's movements during throwing, the coordination of the lower and upper body, and the trajectory of the shoulder, elbow, and fingertips. Furthermore, it's useful for expanding the range of motion of the shoulder blades and for stretching. For daily strengthening and maintenance during the season, cool-downs after practice, muscle training in the rain or bath, and winter training. Use it by having someone hold it or by attaching it to a fixed pillar or leg. This training tube/rubber band supports baseball players from youth baseball, soft baseball, softball, hardball, Little League, Senior League, Boys League, Pony League, Young League, high school baseball, semi-hardball, college baseball, corporate baseball, to professional baseball.
