Coach Cale Owen discusses the kettle bell sumo dead lift in this segment, the movement incresease strength in the hamstrings, glutes and back.  Remember that feeling tension in your hamstrings is not a bad thing when performing the skill, make sure that the kettle bell stays even with your heels at the bottom half of the movement.  Start with 3 sets of 8-10 reps of light weight, as you increase in weight for this skill make sure you drop down on the number of reps that you are doing to 6-8.
