What is the principle of overload in strength training?

Answer 1

This means that you cant keep doing the same weights or sets or reps, you have to increase in progression otherwise your body will adapt and it will become too easy, and then you will plateau. The overload principle is you overload your body with the strength training session, you eat well, you recover enough to do the same again v soon. all the time gradually increasing the factors I mentioned above one at a time only so if you increase weight you reduce reps or sets.
