From Smitty's YouTube page: "Here is a video of some recent kettlebell training. Performing a typical kettlebell press from the racked position, provides an extended range of motion, under tension, for a vertical pressing motion. This, in turn, creates a stable shoulder complex. The BTR (beyond the range) deadlifts are performed to increase the strength mobility (increased range of motion and strength in this new range of motion) of the hips and improves leg drive and glute activation. The chains provide a progressive loading.
Also demonstrated are KB + chain press, KB + chain OHS, trap bar deadlifting + chains."
