The phase that focuses on increasing muscular endurance, strength, and hypertrophy is load training. This phase involves progressively increasing the weight or resistance used during exercises, which directly contributes to building muscle size (hypertrophy) and enhancing the ability of muscles to sustain prolonged activity (Muscular endurance). Additionally, load training helps improve overall strength, as it challenges the body to adapt to heavier weights over time.

In this context, stability and mobility training primarily focuses on improving the body’s ability to stabilize joints and maintain optimal movement patterns, which are essential for effective resistance training but do not directly target muscular endurance, strength, and hypertrophy. Movement training emphasizes developing proper techniques and efficiency in fundamental movement patterns, setting a foundation for later resistance training phases but not specifically targeting muscle gain. Performance training focuses on enhancing athletic performance and may include specific skills and drills aimed at improving speed, agility, and power rather than solely on muscular endurance or hypertrophy.

Thus, load training is the most appropriate choice for the goals specified in the question, as it directly aims to build endurance and strength while promoting muscle growth.
