N. Amer. informal get rid of; destroy utterly. – ORIGIN 1920s (as the deep six ‘the grave’): perh. from the custom of burial at sea at a depth of six fathoms.
The Deep 6 Workout is a takeoff of the old Omelet, but is limited to the SFG core 6 lifts. The Deep 6 allows the trainee to practice and develop deep skill in all of the basic six SFG lifts, hence the name Deep 6. It consists of three different levels and is appropriate for Kettlebell practitioners of varying levels of conditioning. The Deep 6 will be great practice for people looking to gain muscular endurance such as fighters or for people who would just like to up their conditioning level to have an easier time at the SFG. It can also stress-proof the “getup” by practicing it in a pre-fatigued state.
