An exercise apparatus particularly for baseball pitchers for strengthening the pitching arm, the apparatus having a standard, regulation baseball axially secured to a shaft, the opposing end of the shaft having a weighted resistance, the baseball selectively rotatable on the shaft to permit the gripping of the baseball for adapting to different pitching grips, the user gripping the baseball and using a hammer-like action to engage the weighted resistance against a frictionally displaceable resistance such as a dowel or nail.
