This video introduces the "cage" where we are forced to stay low while doing drills. The cage mandates that we stay low and not creep up. Getting low and being comfortable in a crouch is a 1000 mile journey. Staying low requires leg strength, hip mobility and balance. All of these skill sets are not something that can be mastered in a training session, a week or even a year.
