I often see sloppy kettlebell swings at the gym and I restrain myself because I don't want to be that dickwad who gives advice to those who don't ask for it. Without further adieu, the most common mistake I see with the kettlebell swing is the timing.
Before I go further, lets review the phases of the kettlebell swing from the starting point where the kettlebell is grounded and the person is in an American football center position (about to hike the ball).
- The bell is 'hiked' towards the rear until there is sufficient contact between the arms against the body, and tension through both arms. The posterior hips are loaded.
- The hips are extended and driven forward, pushing the kettlebell forward and up, and initiating the swing.
- The bell floats to the desired height while the swinger assumes an erect position, establishing all the tenets of good posture.
- HERE'S THE PART WHERE PEOPLE MESS UP: one maintains an erect position while the kettlebell descends and ONLY BEGINS TO FLEX THE HIPS WHEN THE UPPER ARMS MAKE CONTACT WITH THE RIBS. With such timing, the kettlebell swings back into a position close to the crotch as the swinger returns to the initial hiking position. Unlike conventional exercises where "I go down while the weight goes down," the kettlebell involves a timing where "I stand tall while the weight goes down." I can't emphasize this enough because flexing forward prematurely increases the load on your spine, particularly the lower back. And with improper timing, the exercise becomes a kettlebell 'LIFT' and not a 'SWING'.
I didn't mention anything about posture because the tenets of good posture GO WITHOUT SAYING:
- Neck in neutral while assuming a long spine
- Shoulder blades back and down
- Lower back in neutral, not too arched or flat
