Which exercise is an example of isolated strengthening?

Isolated strengthening exercises target a specific muscle group and are designed to improve strength and function in that particular area, often with minimal involvement from surrounding muscle groups. The quadruped arm/opposite leg raise involves extending one arm and the opposite leg while stabilizing the core, which primarily works the glutes and upper back muscles in a more focused manner compared to compound exercises.

The deadlift, squat, and lateral band walk all involve multiple muscle groups working together. The deadlift and squat are both compound movements that engage major muscle groups throughout the entire body, including the legs and back. The lateral band walk, while targeting specific muscle groups such as the hip abductors, also requires coordination and strength from the lower body as a whole to perform effectively.

In contrast, the quadruped arm/opposite leg raise isolates specific muscles by requiring stabilization and controlled movement, which enhances activation in the target muscles without significantly recruiting other muscle groups. This focus on a singular muscle group and support ability in stabilizing the trunk exemplifies isolated strengthening.
