Adhering to precise execution standards in the conduct of all PRT activities ensures the development of body management and fundamental movement skills. PROGRESSION. Progression is the systematic increase in the intensity, duration, volume, and difficulty of PRT activities. The proper progression of PRT activities allows the body to positively adapt to the stresses of training. When progression is violated by too rapid an increase in intensity, duration, volume or difficulty the Soldier is unable to adapt to the demands of training.
The Advisory Committee concluded that absolute moderate-intensity or vigorous-intensity physical activity is necessary for substantial health benefits, and it defined absolute aerobic intensity in terms of METs: 1  Light-intensity activities are defined as 1.1 MET to 2.9 METs.he intent of the aerobic Guidelines for adults is to ensure that people who follow them generally achieve 500 to 1,000 MET-minutes or more. For this to occur, the definition of intensity in the Guidelines needs to be in terms of METs (i.e., absolute intensity).
