Final answer:
The primary goal for the 21-year-old male client should be to improve his upper body strength, as his bench press figures suggest it is not proportionate to his lower body strength.
Step-by-step explanation:
Given the physical assessment results of the 21-year-old male client, it appears that his upper body strength is the area that requires primary attention. His bench press 1RM (one-repetition maximum) is 200 pounds, which compared to his body weight of 210 pounds and a leg press 1RM of 400 pounds, suggests a disproportion. The relatively lower bench press figure indicates that his upper body strength is not on par with his lower body strength. Additionally, the fact that he can perform 50 sit-ups in one minute demonstrates good muscular endurance and performing 15 inches on the sit and reach test indicates at least average hip/low back flexibility. Therefore, to balance his overall physical profile, focusing on upper body strength would be most beneficial.
