For a client with a desired intensity of 30-60% 1RM, at what number of successfully completed repetitions should you consider increasing the weight?

The correct choice identifies that when a client can perform around 25 repetitions successfully at a given weight within the desired intensity range of 30-60% of their one-repetition maximum (1RM), it indicates that the weight may be too light for their strength level.

In resistance training, particularly for older adults or those undergoing geriatric physical therapy, the general guideline is that performing a high number of repetitions, such as 25, suggests that the muscles are not sufficiently challenged by the current resistance. This number of repetitions is typically associated with muscular endurance rather than strength development, especially when aiming for fitness improvement.

In this context, increasing the weight after achieving 25 repetitions helps to ensure that the training remains within the target intensity of 30-60% 1RM. This adjustment is important as it promotes continued progression and adaptation, ultimately leading to improved strength and functional abilities in geriatric clients.
