In 1990 former assistant Bronx D.A. Tony Abbatine launched Frozen Ropes, a chain of baseball training centers in Chester and White Plains, N.Y., Franklin, Mass., and Guelph, Ont., where customers study what Abbatine calls holistic hitting. "If you know how the body works, you can generate arm speed and bat speed," says Abbatine, who lectures students on centrifugal stability while they take BP on a balance beam and has them wear strobe glasses to hone something called saccadic eye movement. Though his methods are unorthodox, pros including '98 A.L. batting champ Bernie Williams work out at Frozen Ropes. As Abbatine says, "It's what you learn after you think you know it all that counts."
