Comparison kinematic models of the traditional style deadlift are presented. Data was obtained through film and analyzed via computer and computer graphics.

The comparison between the models revealed that the greater-skilled:​

1. used less trunk flexion from the instant of initial trunk lean to the instant of maximum trunk lean,
2. used less knee extension (in same time interval as 1), and
3. demonstrated a smaller horizontal distance between the body center of mass (CM) and the CM of the bar at the instant the bar left the platform.

A trend was also observed in which the greater-skilled subjects demonstrated less thoracic lean than the lesser-skilled group at the time the bar reached knee level.
