#1 muscle confusion: This principle is implemented to trick the muscles. Constantly changing the stress on the muscle forces progression.

#2 split training: This technique divides the muscle groups to be trained on different days. By training only two muscle groups at time, the volume of stress can be doubled or tripled depending on the time allotment.

#3 Strip setting: This technique has the participant executing an exercise to failure, reducing the resistance, and continuing the set to failure, and continuing this process until the muscle is completely fatigued.
