In the OPT model, Phase 2 is primarily focused on strength gains. This phase is known as the Strength Endurance phase, where the primary goal is to increase the individual's overall strength while also improving muscular endurance. The training in this phase typically involves moderately heavy weights lifted for more repetitions, often utilizing compound movements that engage multiple muscle groups.

By focusing on strength gains, individuals can build a solid foundation that supports their future training phases, including power development and more advanced strength adaptations. This phase also emphasizes proper lifting techniques, enhancing the neuromuscular connection and preparing the body for more intense strength training in later phases.

The context in which this phase operates helps individuals to develop the capacity to perform more demanding physical activities, thereby increasing their athletic performance. The design of the workouts is specifically structured to maximize strength adaptation while maintaining muscle endurance, which is crucial for sustained performance in various activities or sports.
