ABSTRACT:
An exercising device having a bat which applies a restraint to the swinging thereof. This may be accomplished with an extendable line held therein or a moveable weight within the bat. The line is tied to a stationary object and as the bat is swung, a spring within the bat increases the resistance on the line. As the bat reaches the area at which it would normally contact the ball, the line is preferably restrained from further extension.
