This is the "standard" Kettlebell Press, this press always starts from under the chin and proceeds to lock out over head, note: "Lock-out" this means elbow is fully extended.

•  In the rack position the fist must be below the chin level
•  The kettlebells must remain in the rack position for a one count before each press
•  Press with the knees locked, the neck neutral, and no back bend
•  Keep the quads, glutes,and midsection tight.
•  The torso may lean slightly back but the lean may not increase during the press
•  The shoulders may not elevate in the range between the rack and the point where the handle is at the eye level
•  The forearms remain vertical or nearly vertical throughout the press
•  The wrist may not hyperextend.
•  Lock out elbows completely and pause motionless
