The Importance of Phase Lung

It's better to vary your workout routine with different weights and sets to target different muscles and prevent wear and tear on your joints. Alternating between heavier and lighter training is optimal for joint health. Phase length refers to the duration of a training program, which typically consists of several weeks of gradually increasing intensity followed by a D load week of easier training. Most people can handle three to five weeks of accumulation before needing a D load week to recover and continue progressing.
