Why are the warm-up exercises so important?
The second part of practice, the warm-up exercises, are important because they prepare your muscles for the type of work they will be doing later in practice and help prevent the kinds of muscle injuries common to many sports activities. Some of the warm-ups involve gentle stretching – since the warm-ups are performed with motion, make sure that only the very mildest of stretching occurs. For improved flexibility, a personal stretching routine using slow stretching is recommended.
