@Gary Le Rosbifs Im glad you’ve asked that because it’s been rattling around in my mind too. Many moons ago, I read a magazine by a powerlifting luminary of that time, possibly Fred Hatfield, but I’ve slept since then. Whoever it was, stated that the body is designed to take any load at any time, which makes perfect sense, and that excessive warm ups merely increase the chance of injury by unnecessarily weakening the muscles before they are subjected to your maximum load of the workout, and that the way to achieve the best amount of stimulation was to start with your maximum load and remove weight each set. Like has been mentioned here earlier, for me it’s about the mind/muscle connection and feeling the groove. I know for a fact, that for me, Whwido warm up principle is the best Ive used. The Cheetah doesn’t perform any movement which is unnatural, whereas there is nothing natural about RT.
