Answer:
When a person increases their exercise routine gradually over time, it is called progressive overload.
Step-by-step explanation:
Progressive overload is a principle in exercise training that involves gradually increasing the demands placed on the body to challenge and stimulate adaptation continually.
By progressively increasing the intensity, duration, or frequency of exercise, you can elicit positive changes in your body, such as increased strength, endurance, and overall fitness. This gradual progression allows your body to adapt and improve without placing excessive stress or risking injury.
