Question

which workout principle encourages you to increase weight to help build strength?
specificity
max day
overload
ego lifting

Explanation:

The overload principle in fitness states that to build strength, the body must be subjected to a greater load than it is accustomed to. This often involves increasing weight. Specificity refers to training a particular skill or muscle group. "Max Day" is not a well - known standard workout principle in general fitness. "Ego Lifting" is not a legitimate workout principle for building strength in a healthy way; it usually refers to lifting weights beyond one's capacity for show.

Answer:

C. Overload
