Which type of training is considered a simplification of PHA training?

Circuit training is considered a simplification of PHA (Peripheral Heart Action) training because both methods involve moving quickly from one exercise to another with minimal rest in between. PHA training targets large muscle groups alternately to enhance cardiovascular efficiency and muscle endurance, while circuit training incorporates a series of exercises designed to elicit a similar effect but typically focuses more on varied exercises rather than a structured rotation of muscle groups.

Circuit training allows participants to engage in multiple types of exercises, often combining strength and aerobic tasks, facilitating an effective full-body workout in a modular format. This structure makes it easier to follow and implement, aligning well with the principles behind PHA training but with less complexity regarding the ordering of exercises and muscle group targeting. This simplification can be beneficial for individuals looking to improve overall fitness without the intricate planning that PHA might require.
