There are six principles of conditioning in the field of exercise science that every athlete or trainer should follow when prepping for the optimal workout or exercise program. These principles are universally accepted and should be followed so that those participating can make the most gains and improvements in their fitness and performance levels.
The second of the six principles is the Principle of Overload, which states that a greater than normal stress or load on the body is required for training adaptation to happen. What this means is that in order to improve our fitness, strength or endurance, we need to increase the workload accordingly.
In order for a muscle (including the heart) to increase strength, it must be gradually stressed by working against a load greater than it is used to. To increase endurance, muscles must work for a longer period of time than they are used to or at a higher intensity.
