Mechanics

Pattern
hinge
Equipment
kettlebell
Geometry
120° Hinge Angle
Energy model
Glycolytic Pathway (10-90s)
Target feel
Power is all hip snap — arms are just a rope; glutes fire at full extension.
Progression
Increase load; progress to single-arm or dead-stop swing.
Regression
Romanian deadlift to nail the hinge before adding the ballistic component.

Watch for

  • Squatting the swing instead of hinging — quads, not hips, do the work
  • Letting the bell pull the lower back into flexion
  • Bending the elbows — lose the pendulum mechanic

Substitutions

  • Romanian deadlift
  • Barbell hip thrust
  • Trap bar deadlift
