Final answer:
The appropriate intensity level for a client aiming to achieve maximal strength in squats is high intensity.
Step-by-step explanation:
The appropriate intensity level for a client aiming to achieve maximal strength in squats would be high intensity.
High intensity exercises are typically performed at 85-100% of the individual's one-repetition maximum (1RM) and involve lifting heavy weights for a lower number of repetitions. This type of training stimulates the muscles to adapt and grow stronger.
By incorporating high intensity squats into their training program, the client can challenge their muscles, increase their overall strength, and improve their ability to lift heavier loads.
