Imagine grabbing a 20-kilogram (44-pound) bag of dog food.
Now try lifting it with one hand.
OK, try two hands.
For a heavier test, say, 30 kilos (66 pounds), try grabbing six full paint can gallons, using one and/or two hands. Now lift.
Do this repeatedly as many times as you can in 10 minutes without dropping the bag or the cans.
Congratulations. You've received a glimpse into the fitness sport of kettlebell, and you can watch some of the best up close and personal in Armstrong as athletes try to land a one-calendar-year reservation on the Canadian Kettlebell Alliance's (CKA) National Team.
