What equipment must be used at Station 4 during PT sessions?

The correct answer highlights the necessity of using either dumbbells or kettlebells at Station 4 during physical training (PT) sessions. These pieces of equipment are versatile and beneficial for a wide array of strength training exercises. They allow for a range of movements that target various muscle groups, which is crucial for developing overall functional strength and improving performance. Additionally, both dumbbells and kettlebells can be adjusted to accommodate different fitness levels by varying the weights, making them suitable for users at different stages of their training.

Using dumbbells or kettlebells also promotes better muscle engagement and core stabilization compared to bodyweight exercises alone, enhancing the effectiveness of the workout. While equipment options like barbells and resistance bands have their own benefits, they are not specified as required for this particular station, which emphasizes the unique value dumbbells and kettlebells bring to the training protocol at Station 4.
