Question

1. functional fitness improves real - life movements by

strengthening muscles by isolating a muscle.
focusing mainly on muscle endurance.
focusing mainly on muscle bulk.
teaching muscles to work together.
teaching lifetime sports skills.

Explanation:

Functional fitness emphasizes training movements that mimic real - life activities. Isolating a muscle (like in some bodybuilding exercises) is not the focus of functional fitness. Muscle endurance is part of fitness but not the main way functional fitness improves real - life movements. Focusing on muscle bulk (hypertrophy) is more related to bodybuilding. Teaching lifetime sports skills is a broader concept. Functional fitness is about teaching muscles to work together in coordinated patterns that are relevant to daily activities. For example, when you pick up a heavy object from the floor (a real - life movement), multiple muscle groups (lower back, glutes, hamstrings, etc.) need to work together. Functional fitness training would mimic such a movement, strengthening the synergy between muscles.

Answer:

teaching muscles to work together.
