The word is composed of 'Körper' (body) and 'Gewicht' (weight). The 's' in between is a linking s, which connects the two words. The meaning is literal: the weight of the body.
Ein gesundes Körpergewicht ist wichtig für das Wohlbefinden.
A healthy body weight is important for well-being.
In connection with body weight, the verbs 'reduzieren' (to reduce), 'halten' (to maintain), 'erhöhen' (to increase), and 'kontrollieren' (to monitor/control) are often used.
Er versucht seit Monaten, sein Körpergewicht zu halten.
He has been trying to maintain his body weight for months.

mass / crowd
'die Masse' and 'das Körpergewicht' are connected because body weight refers to the mass of a living body and is usually given in kilograms. 'Masse' is more general and can be used in physics for all bodies or objects. 'Körpergewicht' is used especially for people and animals, often in everyday life, at the doctor's, or in sports. The words can be confused because both have to do with kilograms. For a person, you normally say 'Körpergewicht'; in physical or technical contexts, 'Masse' fits better.
