Specific adaptions to imposed demands.
You have to continue to change your exercises and routine; otherwise, your body will not change. If you continue to lift 140 pounds on the bench press, overtime you will not see any progression. You have to continue to manipulate the variables (reps, sets, intensity, rest periods, etc) to keep making progress for the specific goal you have.
Here are the rep and set acute variables for the 5 phases of training.
The reps will be done at a slow pace for this goal. The exercises will be performed in a controlled, unstable environment.
A stabilization exercise is performed immediatley after a stregth endurance exercise
This will be done at the same pace as the strength endurance phase.
This will be done at a much faster pace than the hypertrophy phase.
You will superset a max strength exercise followed by a power exercise in this phase.
