We were recently introduced to this kettlebell swing variation by @cfartistry. It is a fantastic variation because the resistance increases as the band length increases. This means we can apply further load to the exercise at the STRONGEST POINT of the KB swing, with fully extended hips and knees. We can really drill home the cue of "snapping the hips," fighting not just the weight of the barbell but also the resistance of the band.
*MAKE SURE YOU TIE THE RESISTANCE BAND AS SHOWN or the band might come loose and snap you in the face!! Also, be sure to keep your feet down the entire time. If your feet come off the band it'll come up and hit you as well!
