The kettlebell deadlift is a foundational movement in kettlebell training. It's often taught as a buildup or regression to the kettlebell swing, as well as to instruct the "hip hinge" motion in a more approachable manner than with a barbell.
Benefits
Simpler and safer to teach than a barbell deadlift because weight is between feet
Strengthens the muscles of the hamstrings, glutes, upper back, and grip
The weight can be elevated on a plate or step to make it easier
Great way to do deadlifts for high reps, or to learn the motion of the deadlift or kettlebell swing
