For a strong, fit body, you can’t go wrong with a strength workout, especially a session that targets one of the body’s powerhouses: the posterior chain. This group of muscles is in the lower back body and includes the glutes, hamstrings, and calves.
Why does strengthening the posterior chain matter? Your posterior chain muscles do most of the heavy lifting in day-to-day activities. They help you stand up and sit down, walk, run, and give you the power to lift heavy items, something known as functional strength. They also help you maintain your balance and posture throughout the day.
