Often during the winter, certain sports and physical exercise are curtailed. Weather sometimes provides the perfect excuse. But with the first warm day of spring, the outdoors beckon once again and unless you are one of the rare people who maintains good physical fitness year-round, a slow, gradual beginning is advised.
Generic preparations apply to most sports.
First, you should fully stretch your muscles and strengthen them gradually while returning to your previous level of athletic activity. Along with physical preparation, the mechanics of the activity are also important. Improper movements, such as overthrowing in softball and baseball, can cause problems. You've got to throw the ball hard, you feel like you're impervious to injury and you push hard. So many times you end up straining or stretching the muscles by not exercising or by not turning the shoulder properly when you pitch.
