pull your weight: meaning and explanation
When you are doing something as part of a team, you are pulling your weight if you are working as hard as you should be working, or contributing as much as the others in the group.
This expression is generally used in the negative, to say that someone is being lazy or not contributing much to a project. This person is not pulling their weight. In these situations, the other members of the group or team have to work harder to compensate for the lazy team member
This expression comes from the sport of rowing. Based on someone’s weight (i.e. their size) you can expect them to ‘pull’ or row with a certain amount of strength. If they contribute less than this, they are not pulling their weight (and their team mates will have to work even harder if they want to be successful).
