Kettlebells go waaay back (19th century!), which means so does the butt-kicking work they cause. So for this workout, put on a little throwback music (“Rock the Bells” would be appropriate) and pour a little sweat out for the peeps that brought us that big ball of iron we have grown to know and love today. This workout includes a warm-up. Multiple-sized KBs are preferred but not required.Do you have a fitness resolution?
