The four types of basic movements that form the foundation of functional fitness are push, pull, squat, and hinge. Pushing movements, like push-ups, strengthen the upper body, while pulling movements, such as rows, build the back and biceps. Squatting movements target the lower body, improving leg strength, promoting better balance, and supporting hip mobility. Hinge movements, like deadlifts, focus on the posterior chain, enhancing overall core strength and stability. Incorporating these fundamental movements into a fitness routine ensures a well-rounded approach to strength development and functional movement.
