The five strength training principles are:
1. Overload- placing increasing amounts of stress on the body causes adaptations that improve fitness.
2. Recovery- the body should adapt to the stress placed upon intense workout sessions
3. Specificity- the adaptations your body will make are specific to the types of exercise stress to which it is exposed
4. Reversibility- you must be consistent in your training efforts in order to achive e resulsts or maintain your fitness level
5. Periodization- long-term fitness plan is a must if you want to work toward fitness-related goals.
