I read all 33 tips plus the bonus tips with great interest. I found the information to be very helpful. I especially liked the discussion of the three forms of muscular exercise for strength training - Isokinetic, Desmodromic and Eccentric. It explains why strength training with the Isokinator is one of the best ways to train for muscular development without compromising joint health. This is important for me as a 72-year-old male. I find that the Isokinator is a superbly manufactured product of the highest quality, and its simplicity and effectiveness is unparalleled as a full-body exercise device of its kind.
