Strength is a skill. Each skilled movement has its invariances, which are fundamental and unchangeable, and surface features, which are adjusted to accommodate to the immediate needs without changing the nature of the movement. Smart athletes leave the invariances alone and play with surface features. If an exercise was repeated many times, it was a standard Soviet sport practice to modify it as a training session went along. In lifting, it meant minor tweaks such as the grip width, the barbell and the feet placement, the bench incline angle, etc. |
