What is progressive intensity training in resistance training?
Progression refers to steady and consistent increase in intensity of an exercise.
In resistance training, intensity refers to the amount of resistance. For example when you progress (steady and consistent) from lifting 100 pounds to lifting 120 pounds, you are increasing the intensity.
What is not progressive resistance training?
Holding a stretch in a painful position or doing so many squats until your thighs burn and you can no loner walk may be an intense experience, but they have nothing to do with resistance training intensity.
Random jumps in intensity and inconsistent changes do not fit the definition of progression we use under Kaizen principle.
Custom workout plan with strong scientific base include a clear progressive resistance training.
