Which of the following options would be the correct superset for back exercises during Phase 2 of the OPT model?

In Phase 2 of the OPT model, which focuses on strength endurance, the goal is to enhance both strength and muscular endurance through more complex movement patterns and exercises. Supersets in this phase are typically designed to target the same muscle group with varying levels of intensity and emphasis on different movement patterns.

The option involving the seated cable row followed by stability ball dumbbell row is particularly effective for this phase. The seated cable row is a controlled, strength-focused movement that allows for the activation of the major muscles in the back with a focus on form and stability. Following this with the stability ball dumbbell row introduces an element of instability, which challenges the stabilizing muscles and encourages greater engagement of core muscles. This combination works well for enhancing both the strength and endurance of the back muscles, fulfilling the objectives of Phase 2.

In contrast, the other options either prioritize different movement patterns that may not complement each other effectively or include variations that do not maximally benefit the specific adaptations sought in that phase. The key in Phase 2 is to create a superset that allows for a dual focus on strength and endurance in a manner that progressively overloads the muscles while maintaining proper form. Thus, the combination of seated cable row and stability ball dumbbell row
