A bodybuilder exercises his biceps by repetitively lifting weight. The biceps get bigger over time. What type of adaptation is occurring?

General Adaptation Syndrome (GAS)

Explanation:

General Adaptation Syndrome - it consists of three main stages that involve the transmission of the body when a person undergoes stress (physiological and psychological).

Three stages of GAS consist of Alarm, resistance, and exhaustion.

Alarm - it is the first stage of GAS thus it involves a stimulus that allows the body to respond quickly to the changes.

Resistance - in this stage changes due to initial threats are repaired.

exhaustion - This stage defined the condition of the body when stress is so harmful that the body cannot able to back to its initial position.
