The lowest connection between the base(s) and the top person is above waist level and below extended level. i.e. prep, shoulder level hitch, shoulder sit. A stunt may also be considered at Prep-Level if the arm(s) of the base(s) are extended overhead, but are NOT considered “Extended Stunts” since the height of the body of the top person is similar to a shoulder/prep level stunt. i.e. flatback, straddle lifts, chair, T-lift. A stunt is considered below Prep Level if at least one foot of the top person is at waist level, as determined by the height/positioning of the base. (Exception: chair, T-lift and shoulder sit are prep level stunts).
