It might. If weightlifting counts for 50% of your total "score" and some hypothetical "worthy" metric (such as coding) counts for 50%, someone scoring a 5/5 on weightlifting but only a 3/5 on coding would have a higher total score than a person who scored 1/5 on weightlifting and 5/5 on coding.

The first guy is not necessarily "unqualified", but he would relative to the other guy. People who were hired for their weightlifting abilities wouldn't have had to reach a higher score on coding in order to get hired. So on average, you would expect them to be less qualified.
