According to Arnold, since his heart surgery, doctors told him heavy lifting was now out of the question. For t-4 he had to rely on more high rep circuit style training to get back into shape. Since he became Governor, training is something that is far less then it used to be. He says he still lifts, but usually only 3-4 days per wk of brief light circuit training, with at least 5 days wk of cardio coming from either recumbent bike or tennis. He says he really misses the heavy lifting, but there is not a lot he can do about that.
This came straight from his mouth.
