To "bulk up" typically involves following a structured training program that emphasizes weight training and resistance exercises designed to stimulate muscle growth.

The purpose of bulking up is to add both muscle and body size. This process often involves gaining some amount of body fat along with the muscle mass, as the surplus of calories required for muscle growth can result in an increase in overall body weight. However, it should be noted that the specific approach to bulking up can vary depending on an individual's goals, body type, and personal preferences.

The phrase "bulk up" is composed of two words: "bulk" and "up", each with its own etymology.
The word "bulk" dates back to the late 14th century and originated from the Middle Dutch word "bolke", meaning "a heap" or "mass". It later evolved to the Old Norse word "bulki", referring to a "cargo" or "ship's load". Over time, "bulk" expanded to its current meaning of "volume" or "size".
The word "up" has a much older origin and can be traced back to Old English as "uppa" or "upp", indicating a vertical direction or upward movement.
When used together, "bulk up" suggests increasing body mass or muscular size through physical training or weightlifting exercises. The phrase implies adding "bulk" to an individual's physique, and "up" emphasizes the upward growth or enlargement of muscles.
