The 80g limit is a rule that was put in place to help prevent people from over-exerting themselves during exercise. This limit is the maximum amount of weight that a person can lift in a single repetition. It is important to note that this limit is not a hard and fast rule, and that people can still lift more than 80g if they feel comfortable doing so. However, it is generally advised that people stick to the limit in order to avoid injury.
