Bootcamp = a short period of time (a week or so) where you do a lot of exercise and training to toughen you up.

Eliot is right , as the informal meaning of "bootcamp" is a series of difficult exercises done over a specific period of time. The dictionary definition of "bootcamp" is: 1. A training camp for military recruits. 2. A correctional facility that uses the training techniques applied to military recruits to teach usually youthful offenders socially acceptable patterns of behavior.
