Share 'Kettlebells'

I would like to know how many of you actually incorporate kettlebells into your strength programs??? I have found them to be an excellent tool to gain coordination and explosiveness in my athletes. So much so that I attended Pavel Tsatsouline's Russian Kettlebell Challenge Certification and am now the only Certified Kettlebell instructor in my area. P.S. its a pretty good program for us old farts…
