The Kettle Bell Swing.....

Saw a fellow in the gym who seemed to have his arms at his elbows locked on the swing, it made me wonder which is proper. I like the view that when you do the kettlebell swing, you're arms act like ropes or cables holding the kettlebell while your legs, knees and hips do most of the work.

This, arms are like cables...

VS. this:

Which is somewhat similar to what the person in the gym did.

1- Stand straight with your legs shoulder width apart and the kettlebell between your legs.
2- Hold the kettlebell with both hands.
3- Swing the kettlebell up using power thrusts from the hip, thigh and your lower back muscle.
3- Swing it back and forth for 3 to 5 sets of 20 to 30 repetitions

But this website says that that is a "crap" kettlebell swing. http://kettlebellfitnessdk.wordpress.com/2011/11/12/kettlebell-swings-and-common-mistakes/


Other images... so I think the cables have it.
